Abigail built 10 fences. Each fence took her 30 minutes to build. If she builds fences for the next 8 hours, how many fences would she have built in total? Give the rationale and then the answer.
Let's think step by step. 8 * 60 = 480 minutes are in the next 8 hours. Abigail builds 480 / 30 = 16 fences. Abigail will have built 10 + 16 = 26 fences in total.. The answer is: 26.

Ivy baked 20 cupcakes in the morning and fifteen more cupcakes in the afternoon than in the morning. How many cupcakes did she bake? Give the rationale and then the answer.
Let's think step by step. In the afternoon, she baked 20 + 15 = 35 cupcakes more cupcakes. Therefore, she baked a total of 20 + 35 = 55 cupcakes.. The answer is: 55.

Jerry is sweeping up pieces of broken glass in the parking lot. He sweeps up 20 amber pieces, 35 green pieces, and some clear pieces. If the green pieces are 25% of the total glass he sweeps up, how many pieces were clear? Give the rationale and then the answer.
Let's think step by step. First find the total number of glass pieces Jerry sweeps up: 35 green pieces / .25 = 140 pieces. Then subtract the number of pieces of other colors: 140 pieces - 20 pieces - 35 pieces = 85 pieces.. The answer is: 85.
