For a class fundraiser, 30 students were asked to bring in 12 brownies each. 20 students were asked to bring in 24 cookies each and 15 students were asked to bring in 12 donuts each. If they sell everything for $2.00 each, how much money will they raise? Let's answer step by step:
30 students were asked to bring in 12 brownies so they will bring in 30 * 12 = 360 brownies. 20 students were asked to bring in 24 cookies each so that's 20 * 24 = 480 cookies. 15 students were asked to bring in 12 donuts each so that's 15 * 12 = 180 donuts. Together, they have 360 + 480 + 180 = 1,020 treats. If they sell all the treats for $2.00 each then they will make 1020 * 2 = $2,040.00. The answer: 2040.
