Group Title
Luke trades working at the barn for riding the horses. This week he rode for 3.5 hours, which is 4.5 less than twice the number of hours he worked. How many hours did he work this week? Let h = the number of hours he worked.
A. 4.5  2(3.5) = h; h = 2.5 B. 2(3.5)  4.5 = h; h = 2.5
C. 3.5 = 4.5  2h; h = 0.5 D. 2(3.5)  4.5 = h; h = 2.5

This week he rode for 3.5 hours, which is 4.5 less than twice the number of hours he worked translates to 3.5 = 4.5  2*(number of hours worked) so what is your equation?
