Question

Joe earns $9 per hour. He worked x hours on both Wednesday and Friday, and 8 hours on both Tuesday and Saturday. Write an expression to represent how much Joe earned. Justify your answer.

Answer 1

Joe earns 18x+144 dollars that week with x being the number of unknown working hours on Wednesday and Friday.

Explanation:

Joe earns $9/hour, On wednesday and friday he worked a total of 2x hours and on Tuesday and Saturday he worked a total of 16 hours. Let y be the amount of money Joe earned.

To determine how much money Joe earned we must determine how much hours he has work:

=
`2*x+2*8=2*x+16`

We can determine the amount earned from the total amount of hours work and rate of $9/hour:

`y=(2*x+16)*9=18*x+144`

Answer 2

To find the total amount earned, you need to multiply the number of hours worked by the pay rate. Joe worked x hours for 2 days. That’s 2x hours. He worked 8 hours for 2 days. That’s 8(2), or 16 hours. The total number of hours he worked is 2x + 16. He gets paid $9/hour, so an expression for the total amount earned is 9(2x + 16), or 18x + 144.
