The total entrance fee for a group of 4 adults and 3 children to a water park is $220. The total fee for a group of 2 adults and 1
child is $98. Determine the entrance fee for an adult and the entrance fee for a child.
a. Select the system of equationslokat model the situation. Solve by using substitution.
Answer:
A.
Step-by-step explanation:
The entrance fee of an adult is equal to $37 and the entrance fee of a child is equal to $24.
What is a system of equations ?
A system of equations is a set or collection of equations that you deal with all together at once.
It is given that :
The total entrance fee for a group of 4 adults and 3 children = $220
and
The total entrance fee for a group of 2 adults and 1 child = $98
Let's assume that the entrance fee for an adult is x and entrance fee for a child is y.
So , the equations can be written as :
4x + 3y = $ 220 --- --- --- --- --- ---- ---- ---- ------ ----- ----Equation 1
2x + y = $ 98 --- --- --- --- --- ---- ---- ---- ------ ----- ----Equation 2
Now , multiply equation 2 by 2 :
4x + 2y = $ 196 --- --- --- --- --- ---- ---- ---- ------ ----- ----Equation 3
Subtracting equation 3 from equation 1 , we get :
(4x - 4x) + (3y - 2y) = $220 - $ 196
y = $24
or entrance fee of a child is $24.
Now , substituting the value of y in equation 1 , we get :
4x + 72 = $220
4x = 148
x = $37
or entrance fee of an adult is $37.
Therefore , the entrance fee of an adult is equal to $37 and the entrance fee of a child is equal to $24.

The rate of change is also known as the slope or rise / run.
Slope Formula: (y2 - y1) / (x2 - x1)
First, we'll need two points that are on the line. You can choose any two points you want, as long as they are on the line.
Point 1 = (0, 1)
Point 2 = (-2, -3)
Then, we'll plug the two points into the formula and solve for the slope.

whats 186,282 rounded to the nearest thousand ?
Answer: 186,000
Step-by-step explanation:
You round the 282 down so that it is an even thousand. <3
186,282 rounded to the nearest thousand is 186,000.
To round 186,282 to the nearest thousand, we look at the digit in the thousands place, which is '6'.
If the digit in the hundreds place is 5 or greater, we round up. If it is less than 5, we round down.
In this case, since the digit in the hundreds place is '8', which is greater than 5, we round up.
To round up, we increase the digit in the thousands place by 1 and replace all the digits to the right with zeros.
Therefore, rounding 186,282 to the nearest thousand gives us 187,000.

f(x) = -2x + 2
Put x = 1
f(1) = -2(1) + 2
f(1) = -2 + 2
f(1) = 0
Put x = 0
f(0) = -2(0) + 2
f(0) = 2
Put x = -1
f(-1) = -2(-1) + 2
f(-1) = +2 + 2
f(-1) = 4
Put x = 2
f(2) = -2(2) + 2
f(2) = -4 + 2

Answer:
Hey girl! I got you.
Step-by-step explanation:
So! The angle x and z are congruent, meaning that they are equal, so you got that part correct. They are indeed 103. Next you need to find y, and in this case you need to do 180 - 103 because the line that holds both angle z and angle y is equal to 180.
180 - 103 = 77, you got that correct also!
You're on the right track, just explain in words how you know what each angle is equal to! Good luck! :)

Chloe works in a department store selling clothing. She makes a guaranteed salary of $250 per week, but is paid a commision on top of her base salary equal to 10% of her total sales for the week. How much would Chloe make in a week in which she made $975 in sales? How much would Chloe make in a week if she made xx dollars in sales?
Answer:
See Below
Step-by-step explanation:
Making $250/week in salary and 10% of the $975 in sales.
First find what 10% of $975 equals. The decimal equivalent of 10% is 0.10
So multiply the decimal and total sales.
0.10 x 975 = 97.5
Her weekly salary plus the commission would be:
$250 + $97.50 = 347.50
If you don't know her sales for the week, you can use X to represent the sales. The equation would be:
0.10x + 250 = y where y is her total pay.
