Answer:
Jennifer paid $108
Step-by-step explanation:
First you have to figure out how much Jennifer's parents paid. In order to do that you will have to do:
180 * 40 = 7,200 Then do: 7,200 / 100 which is 72 OR YOU CAN:
40 / 100 = .40 Then do : .40 * 72 which is 72
So Jennifer's parents paid $72.
So now you figured out how much Jennifer's parents paid, so to figure out how much Jennifer paid do:
180 - 72 which is $108.
This is how you know how much did Jennifer pay.

Answer:
Her uncle's age = 47 years
Step-by-step explanation:
Sophia = 12 years old
Her Uncle Reynald tells her that if she adds 5 to her age,
= 12 + 5
multiplies the sum by 3
= (12 + 5) × 3
and then subtracts 4 from the product
= {(12 + 5) × 3} - 4
she will find his age
{(12 + 5) × 3} - 4
= (17 × 3) - 4
= 51 - 4
= 47
Her uncle's age = 47 years
Sophia wrote:
12 + 5 × 3 − 4
Using PEMDAS
P - product
E - exponent
M - multiplication
D - division
A - addition
S - subtraction
Sophia's expression can be written as = 12+(5*3)-4
= (12 + 15) - 4
= 27 - 4
= 23
Sophia's expression is wrong
Step-by-step explanation:
We can make 2 equations as follows:
2x = y + 16 and x + 2y = 18
x + 2y = 18 is the same as x = 18 - 2y. Hence, 2(18 - 2y) = 2x = y + 16.
2(18 - 2y) = y + 16
36 - 4y = y + 16
5y = 20
y = 4.
