## montrealgurl 2 years ago 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?

3. montrealgurl

is it A?

4. jim_thompson5910

no that's incorrect

5. jim_thompson5910

replace "number of hours worked" with "h"

6. jim_thompson5910

you can do this because you made h = number of hours worked

7. montrealgurl

sorry I meant B. I didn't mean to say A.

8. jim_thompson5910

btw, choices B and D are identical is this a typo?

10. jim_thompson5910

ok i see where the real answer is now

11. jim_thompson5910

it should be 3.5 = 2*(number of hours worked) - 4.5

12. montrealgurl

C!

13. jim_thompson5910

correct

14. montrealgurl

Dang. i was going to say that instead of B. i got all the letters confused. Thanks for explaining!
