which one? All Three you have a issue on?
Well hopefully the following helps...
4)
C =50(h) + 25
C= 50(8)+25 (8 hours)
C= 50(10)+25 (10 hours)
5)
P(ounds) =25 (per week) + 100
400 =25(week) + 100 (how much for 400 pounds) minus both sides 100 then divide both sides by 25..your answer is 12 weeks on that.
6)
C(ost) = 30(x amount of units) + 20. Your Y is the cost.
