Express your answer in hours to 2 significant figures."

I'm not sure how to start the problem. I tried something like:

10(h) + ??? = 275 hours but that doesn't seem like the right equation.

**Reiny**, Friday, June 24, 2011 at 1:25pmlet the number of overtime hours be x

275 = 10(20) + 15x

solve for x

I got x = 5

check

20 hours at $10 = 200

5 hours at $15 = 75

total = 275 , yeahhh

**Reiny**, Friday, June 24, 2011 at 1:39pmwhat is 1.5 of $10 ?

20 hours at $10 = 20(10) = 200

x hours at $15 = x(15) = 15x
