Clive is buying olives for dinner. He has $10 to spend and needs 80 olives. A jar of 20 olives costs $1.50. How much change will Clive have when he buys what he needs?
He needs 4 jars of olives because 80 / 20 = <T>divide(80, 20)=4.0
He will spend $6 because 4 x 1.5 = <T>multiply(4, 1.5)=6.0
He will have $4 in change because 10 - 6 = <T>subtract(10, 6)=4
