You opened a bank account at the beginning of the month and have added the same amount of money each day. On the 5th day, you have $80. On the 21st day, you have $160. How much did you originally open the account with? How much are you putting in the account each day? How much will you have on the 30th day of the month?
Answers
We are given:
Money on the fifth day (a₅) = $80
Money on day 21 (a₂₁) = $160
To Find:
Money in the bank on the first day (a₁) = ?
Money being added to the account per day (d) = ?
Money in the bank on day 30 (a₃₀) = ?
__________________________________________________________
Finding the money on day one and the money added:
Solving for equations
Since we are adding a constant amount to our account every day, the amount of money in the bank can be represented by an AP
We know that the formula for the nth term of an AP is:
aₙ = a₁ + (n-1)d
So, we can write the amount of money on day 5 as:
a₅ = a₁ + (5-1)d
a₅ = a₁ + 4d
80 = a₁+ 4d [We are given that a₅ = 80]
We are also given the amount of money on day 21:
a₂₁ = $160
Money on day 21 can be rewritten as:
a₂₁ = a₁ + (21-1)d
160 = a₁ + 20d [Since a₂₁ = 160]
Solving the equations:
Now we have 2 equations. We will now solve them to get the values of a₁ and d
160 = a₁ + 20d ----------------------(1)
80 = a₁ + 4d--------------------------(2)
From equation (2), we can say that:
a₁ = 80 - 4d [subtracting 4d from both sides]
Now, we will use this value of a₁ in the equation (1):
160 = a₁ + 20d
160 = (80-4d) + 20d
160 = 80 + 16d
80 = 16d [subtracting 80 from both sides]
d = 5 [dividing both sides by 16]
Now that we know the value of d, we can use it in any of the 2 equations:
80 = a₁ + 4d
80 = a₁ + 4(5) [since d=5]
80 = a₁ + 20
a₁ = 60 [subtracting 20 from both sides]
Now, we know the values of the initial amount of money and the money added to the account everyday
Initial money in the bank = $60
Money added everyday = $5
__________________________________________________________
Money in day 30:
We will use the AP formula to find the value of money on day 30
a₃₀ = a₁ + (30-1)d
We know that a₁ = $60 , d = $5
a₃₀ = 60 + 29(5)
a₃₀ = 60 + 145
a₃₀ = $205
Money on day 30 = $205
Answer:
started with $55
adds $5 each day
$205 on the 30th day
Step-by-step explanation:
21-5 = 16
160-80 = 80
80 divided by 16 = 5
5 * 5 = 25
80 - 25 = 55
9 * 5 = 45
160 + 45 = 205
An online clothing company sells custom sweatshirts. The company charges $ for shipping plus $ for each sweatshirt. Write a linear function rule that models the total cost y (in dollars) for any number of sweatshirts x.
Answers
Complete question :
An online clothing company sells custom sweatshirts. The company charges $4.99 for shipping plus $7.50 for each sweatshirt. Write a linear function rule that models the total cost y (in dollars) for any number of sweatshirts x.
Answer:
y = 7.50x + 4.99
Step-by-step explanation:
Given that :
Shipping fee = 4.99
Cost per shirt = 7.50
Writing the relation in the form of a linear equation :
General form of a linear function :
y = mx + c
Where m = slope ; c = intercept
The total cost of ordering x sweatshirts :
y = (cost per sweatshirt * number ordered) + shipping fee
y = 7.50x + 4.99
Answer:
the answer is $7.99

y = - 9/3 - 8x/3
Rearrange
y = - 8x/3 - 3
The slope is the coefficient of x which is - 8/3

what is the slope of the 2 points (10,15) (6,23)
Answers
Answer:
The slope is -2.
Step-by-step explanation:
m=y2-y1/x2-x1 (also, y1-y2/x1-x2 is also true.)
=23-15/6-10 m=15-23/10-6
= 8/-4 =-8/4
=4/-2 =-4/2
= 2/-1 =-2/1
m=-2 m=-2
Consider this equation.
7.8 + 2(0.75m + 0.4) = -6.4m + 4(0.5m - 0.8)
Mia solved the equation and determined that m = 2. Is she correct?
She is incorrect because when substituting 2 for m the result was a true statement.
She is incorrect because when substituting 2 for m the result was a false statement.

Answer:
The slope of the given line is -4
Step-by-step explanation:
The formula of the slope of a line passes through points (x1, y1) and (x2, y2) is m = [tex]\frac{y2-y1}{x2-x1}[/tex]
In the given figure
∵ The line passes through the points (-6, 5) and (-4, -3)
∴ x1 = -6 and y1 = 5
∴ x2 = -4 and y2 = -3
→ Substitute them in the formula of the slope above
∵ m = [tex]\frac{-3-5}{-4--6}[/tex]
∴ m = [tex]\frac{-8}{-4+6}[/tex]
∴ m = [tex]\frac{-8}{2}[/tex]
∴ m = -4
∴ The slope of the given line is -4

The tennis team has played 28 matches so far this season. They have won 10 matches so far. How many matches will the team need to win for the team to have a 55% success rate?
Answers
Answer: they would have to win 22/40 games
Step-by-step explanation:
22 divided by 40 is 0.55 or 55%
Answer:
x = 12 (I took the FLVS assignment for 04.04, and I'll show you guys how to do this!)
Step-by-step explanation:
The team has completed 28 matches so far and has won 10 of them.
The current success rate is:
[tex]r=\frac{10}{28} *1.00=.35714[/tex]
(1.00 = 100% and .35714 = 35.714%)
We need the success rate to be 55%
Then the team must win a number of "x" matches, so:
[tex]r=\frac{10+x}{28+x} =0.55[/tex]
Now we solve the equation for x:
[tex]\frac{10+x}{28+x} =0.55[/tex]
[tex]10+x=0.55(28+x)[/tex](distributive property here!)
[tex]10+x=15.4+0.55x[/tex]
Now, move the 0.55x to the other side by subtracting it from both sides:
[tex]10+x-0.55x=15.4[/tex]
And move the 10 by doing the same thing (subtracting from both sides):
[tex]x-0.55x=15.4-10[/tex]
[tex]0.45x=5.4[/tex]
(You might ask: 15.4 - 10 = 5.4, but how do you get 0.45x out of x - 0.55x? Use Quick Math, and you should get the answer!)
[tex]x=\frac{5.4}{0.45}[/tex]
[tex]x = 12[/tex]
So, by following these steps, x = 12 is your answer!
The team must win 12 matches to have a success rate of 55%.
Hope this helps! Have a wonderful day!
