Answer the following question.
Ashley had already blown up 12 balloons for the party when Andy took over and started blowing them up at a rate of 2 every five minutes. When Andy stopped, there were 50 balloons. For how many minutes did Andy blow up balloons?
Step-by-step reasoning process: Andy blew up 50 balloons – the 12 balloons Ashley blew up = 38 balloons. We know how long it took Andy to blow up 2 balloons, so 38 balloons / 2 = 19 time increments. We know the time increment is 5 minutes, so 19 x 5 minutes = 95 minutes.
The answer is 95.

Answer the following question.
Crystal wanted to sell everything left in her pastry class before closing for the night. She reduced her $3.00 cupcakes and her $2.00 cookies by half. How much money did she make if she sold the last 16 cupcakes and 8 cookies?
Step-by-step reasoning process: She reduced the price of the $3.00 cupcakes by half so they are now 3 / 2 = $1.50. She reduced the price of the $2.00 cookies by half so they are now 2 / 2 = $1.00. She sold 16 cupcakes at $1.50 each so she made = 16 * 1.50 = $24.00. She sold 8 cookies at $1.00 each so she made 8 * 1 = $8.00. She made $24.00 from the cupcakes and $8.00 from the cookies for a total of 24 + 8 = $32.00.
The answer is 32.
