Oliver has $40 and 200 quarters. If he gives his sister $5 and 120 quarters, how much money in total is he left with?
The 200 quarters equals 200*$0.25 = $<T>multiply(200, 0.25)=50.0
Oliver has a total of $40+$50 = $<T>add(40, 50)=90
He gives his sister 120*$0.25 = $<T>multiply(120, 0.25)=30.0 in total from the quarters.
The total amount he gave to his sister is $30+$5= $<T>add(30, 5)=35
Oliver is left with $90-$35 = $<T>subtract(90, 35)=55
