Mary made 242 for 11 hours of work.

At the same rate, how much would she make for 9 hours of work?

1 answer

To find out how much Mary would make for 9 hours of work at the same rate, we can set up a proportion:

11 hours of work = $242
9 hours of work = x (unknown amount)

11/9 = 242/x

Cross multiply:
11x = 9 * 242
11x = 2178

Divide by 11 to solve for x:
x = 2178 / 11
x = 198

Therefore, Mary would make $198 for 9 hours of work.
