Question

You have $20 to spend. You go to the store and buy a bouncy ball for an unknown amount of money and then you buy a glider airplane for $3. If you have $15 left over, how much did you spend on the bouncy ball?

Answer 1

Answer: Let's start by subtracting the cost of the glider airplane from the total amount of money you started with:

$20 - $3 = $17

We know that you spent $15 of that $17 on the bouncy ball, since you had $15 left over after buying both items:

$17 - $15 = $2

Therefore, you spent $2 on the bouncy ball.

Answer: $2.
