The manager of an art supply store decides to hold a Buy 2, Get 1 Free sale on tubes of watercolor paints. The sale is held for one week and a total of 280 tubes of paint were sold (not including the ones given away for free). If each tube of watercolor paint cost the store $7.25, how much money did the store lose by giving away the free tubes of paint?
Answers
Answer:
$1015
Step-by-step explanation:
280 divided by 2 140 times $7.25 is $1015
The amount of money that the store lose by giving away the free tubes of paint is $1015.
Since the manager held Buy 2, Get 1 Free sale on tubes of watercolor paints, then when 280 tubes of paints are sold, 1/2 × 280 = 140 tubes of paints will be given out for free.
Therefore, the amount lost will be calculated by multiplying the number of paints given out by the price. This will be:
= 140 × $7.25
= $1015
Therefore, the amount of money that the store lose by giving away the free tubes of paint is $1015.

Step-by-step explanation:
A scientist has two acid solutions: Artesia, which is a $70\%$ acid solution, and Borromeo, which is a $20\%$ acid solution. (a) Find the amount of Artesia (in mL) that must be added to $500$ mL of Borromeo in order to produce a $60\%$ acid solution. (b) Find the amount of Artesia and Borromeo (in mL) that can be combined in order to form a $100$ mL solution that is $55\%$ acid. (c) Does there exist a combination of Artesia and Borromeo that is $80\%$ acid?
Answers
Answer:
(a) 2000 mL
(b) 70 mL, 30 mL
(c) No
Step-by-step explanation:
Given that Artesia is a 70% acid solution, and Borromeo is a 20% acid solution.
(a) Let x mL of Artesia is added to 500 mL of Borromeo to produce a 60% acid solution.
So, 70% of x + 20% of 500 = 60% of (x+500)
[tex]\Rightarrow 0.7 \times x + 0.2 \times 500 = 0.6 \times (x+500) \\\\\ \Rightarrow 0.7 \times x + 0.2 \times 500 = 0.6 \times x+0.6 \times500\\\\ \Rightarrow 0.7 \times x -0.6 \times x= 0.6 \times500- 0.2 \times 500 \\\\ \Rightarrow (0.7-0.6) \times x = (0.6-0.2) \times500\\\\\Rightarrow 0.1 \times x = 0.4 \times500\\\\[/tex]
[tex]\Rightarrow x = (0.4 \times500)/0.1=2000[/tex] mL.
(b) Let x mL of Artesia and y mL be combined in order to form a 100 mL solution having 55% acid solution.
So, x+y=100\Rightarrow y= 100-x
And, 70% of x + 20% of y = 55% of (100)\\\\
[tex]\Rightarrow 0.7 \times x + 0.2 \times (100-x) = 0.55 \times 100\\\\\Rightarrow 0.7 \times x + 0.2 \times 100- 0.2 \times x = 0.55 \times 100\\\\\Rightarrow 0.7 \times x -0.2 \times x= 0.55 \times100- 0.2 \times 100 \\\\\Rightarrow (0.7-0.2) \times x = (0.55-0.2) \times100\\\\\Rightarrow 0.5 \times x = 0.35 \times100\\\\[/tex]
[tex]\Rightarrow x = (0.35 \times100)/0.5=70[/tex] mL.
and y= 100-x= 100-70=30 mL.
(c) Let x mL of Artesia and y mL of Borromeo be combined in order to make 80% acid solution.
And, 70% of x + 20% of y = 80% of (x+y)
[tex]\Rightarrow 0.7 \times x + 0.2 \times y= 0.8 \times (x+y)\\\\\Rightarrow 0.7 \times x + 0.2 \times y = 0.8 \times x +0.8 \times y\\\\\Rightarrow (0.7-0.8) \times x = (0.8-0.2) \times y\\\\\Rightarrow -0.1 \times x = 0.6 \times y \\\\\Rightarrow \frac {x}{y} = -6 \\\\[/tex]
As x and y are amount of Artesia and Borromeo, so x>0 and y>0
[tex]\Rightarrow x/y >0[/tex], so the negative value of x/y is not possible.
Ad the negative value of x/y is not so x/y=-6 is not possible, hence, any combination of Artesia and Borromeo that is 80% acid solution is not possible.

Simplify: 5(x+6)−(5−x)−6x
Answers
Answer:
25
Step-by-step explanation:
5(x+6)−(5−x)−6x
Remember PEMDAS
P – Parentheses
E – Exponents
M – Multiplication
/D – Division (whichever comes first from left to right)
A – Addition
/S – Subtraction (whichever comes first from left to right)
First, let's distribute the left side:
5 * x = 5x
5 * 6 = 30
5x + 30
Now, lets distribute the right side
-(5 - x) = -1(5 - x)
-1 * 5 = -5
-1 * -x = x ( - * - = +)
x - 5
Now we have:
5x + 30 + x - 5 - 6x
Let's combine like terms.
5x, -6x, and x are like terms. 5x + x = 6x - 6x = 0
30 and -5 are like terms. 30 - 5 = 25
25
Since we can't simplify this any further, that is our answer.

Keisha is reading a 325-page book at a rate of 25 pages per day. Use a point-slope equation to determine wheatger she will finish reading the book in 10 days
Answers
Answer:
she can't finish reading the book in 10 days
Step-by-step explanation:
Given that:
Number of pages = 325
Number of pages read per day= 25
Using the linear relation:
y = mx + c
y = number of pages left
m = reading rate ; c = initial number of pages
y = - 25x + 325
Point slope relation :
y - y1 = m(x - x1)
m = slope
We can factorise the equation to the point slope form:
y - 325 = 25(0 - 10)
y - 325 = 0 - 250
y - 325 = - 250
y = - 250 + 325
y = 75
Hence, number of pages left after 10 days = 75, thus she can't finish reading the book in 10 days

Step-by-step explanation:
The unknown is the hour time: 120+50.30x=250+38.70x. Now solve it: Subtract 38.70 and 120 from both sides and you get 11.6x=130 x=130/11.6 or 11.2 (about)
So the answer is 11.2 hours. Hope this helps :D

about, X = 11.21 (to the nearest tenth)
Step-by-step explanation:
50.30x + 120 = 38.70x + 250 (Given)
Move variables to the right and constants to the left by subtracting both sides.
11.6x = 130 (subtraction Property of equaity)
x = 11.2068965517 (Division property of equality)

13 of the 18 players on the varsity soccer team are seniors. What percent of the players on the team are not seniors?
Answers
Answer:
27.7778
Step-by-step explanation:
If 13 out of 18 players are seniors then 5 of them are not.
To find the percentage you do (5/18) ⋅ 100
5 divided by 18 gives us 0.27777778
Then we multiply by 100 (or move the decimal point two spaces to the right)
The result should be 27.7778%
