A:
Answer:See explanationStep-by-step explanation:1. 400 students in total.Category 1: Students which rode the bus (180)Category 2: Students that were freshmen (115)Let x be the number of students in both categories. Then180 - x students rode the bus and were not freshmen115 - x students were freshmen and didn't ride the busSo, 115 - x = 25x = 90Thus, 90 students rode the bus and were freshmen 90 students rode the bus and were not freshmen 25 students were freshmen that did not ride the bus 400 - 90 - 90 - 25 = 195 students didn't rode the bus and were not freshmen2. 350 students in total.Category 1: Students bought pizza (168)Category 2: Students that were sophomores (123)Let x be the number of students in both categories. Then168 - x students that bought pizza and were not sophomores123 - x students were sophomores and didn't buy pizzaSo, 123 - x = 32x = 91Thus, 91 students bought pizza and were sophomores 77 students bought pizza and were not sophomores32 students were sophomores that did not buy pizza 350 - 91 - 77 - 32 = 150 students didn't buy pizza and were not sophomores
