Lizzy: 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?.
Me: Hmmm, let me think. I think this is the detailed solution:

He needs 4 jars of olives because 80 / 20 = 4. He will spend $6 because 4 x 1.5 = 6. He will have $4 in change because 10 - 6 = 4. Final answer: 4.
