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? Let's answer 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: 85.
