Answer:
A, 38, 40
Step-by-step explanation:
a. A has to be the first graph because it starts at $ 25 and it rises as more work needs to get done
b.if you go from 50 up until you get to the line, then look left at the axis is about $38
c. C=25+s*0.25, substitute c=35 and find s
35=25+s*0.25 subtreact 25 from both sides
35-25= s*0.25
10=s*0.25 divide both sides by 0.25
10/0.25=s
40=s
