Question

Ethan makes $6 per hour mowing lawns and $7.50 per hour bagging groceries. Last week, he made a total of $129. The difference between the number of hours bagging groceries and the number of hours mowing lawns was 10.

Part 1: Select the equation(s) that would represent the scenario above. Select all that apply.

Responses

y=x+10
y is equal to x plus 10

x−y=10
x minus y is equal to 10

7.50x+6y=129
7 point 5 0 x plus 6 y is equal to 129

6x+7.05y=129
6 x plus 7 point 0 5 y is equal to 129

y−x=10
y minus x is equal to 10

y=−x+10
y is equal to negative x plus 10
Question 2
Part 2: How many hours did Ethan spend mowing lawns?
hours mowing

Answer 1

Part 1 — correct equations:
- y = x + 10
- y − x = 10

(These both express that bagging hours exceed mowing hours by 10. The correct money equation with x = mowing and y = bagging is 6x + 7.5y = 129, which was not listed.)

Part 2 — hours mowing:
4 hours.
