Question

Rose bought twelve bouncy balls, each costing 64 cents. She paid for them with 10 dollars. How much money does Rose have leftover? Could she afford another bouncy ball? If so, how many?

Answer 1

Rose will have 2.32$ leftover. She is able to get 3 more bouncy balls.

Explanation:

To get the cost of 12 bouncy balls - 12*0.64 = 7.68$

To get the leftover amount - 10.00-7.68 = 2.32$

To find how many more bouncy balls she could get - 2.32/0.64 = 3.625 which is then 3 bouncy balls because you cannot buy .625 of a bouncy ball.
