On a construction project, you estimate a total of 80 hours of labor. You will work 40 of the hours. Assistant A will work 25 ho
urs. Assistant B will work the remaining hours. You earn $22 per hour. Assistant A earns $15 per hour. Assistant B earns $10 per hour. Altogether, how much is labor going to cost for this project?
It says 2 significant figures so the least it can possibly be is 0.5 less and the most it can be is 0.5 more as if it was, lets say 20.4 it would round down to 20 not 21.
