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. How many hours did Ethan spend mowing lawns?

Respuesta :

Let x be the number of hours of nagging groceries spent by Ethan. With this representation, the number of hours for moving lawns will be x + 10. The equation that would let us solve this item is,
                6x + 7.50(x + 10) = 129
The value of x from the equation is 4. Thus, the number of hours spent for moving lawns is 14 hours.
