Evelyn is trying to make extra money on her summer vacation from school. She works two different jobs, earning $11 per hour washing cars and $13 per hour
clearing tables. How much money would Evelyn earn in a week in which she worked
3 hours washing cars and 7 hours clearing tables? How much money would Evelyn
earn in a week in which she worked x hours washing cars and y hours clearing
tables?

Washing Cars: $33

Clearing Tables: $91

Step-by-step explanation: Multiply 11 by 3, and multiply 13 by 7. I hope I helped!

Step-by-step explanation:

for every 1 hour she works she gets 11 dollars washing the cars, so you multiply the number of hours by the amount of money she gets each hour. Like so,

11 x 3 = 33, so 33 dollars from washing cars

next - 13 x 7 = 91 dollars from house cleaning

add together the amount of each so, 33 + 91 = 124, 124 is the answer.

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
