Carl wants to buy a new coat that is quite expensive. He saved $25 each week for 6 weeks.  On the seventh week, he had to use a third of his saving to pay some bills. On the eighth week, his dad gave him some extra money for him to buy his dream coat. If the coat cost $170, how much money did his dad give him?
Carl saved in 6 weeks $25/week x 6 weeks = $<T>multiply(25, 6)=150
On the seventh week, he ended up having to pay in bills $150/3 = $<T>divide(150, 3)=50.0
His savings were then $150 - $50 = $<T>subtract(150, 50)=100
His dad gave him $170 – $100 = $<T>subtract(170, 100)=70
