Q1) a)1/2 x 132 = 66 - The amount of people paying $40.60
66 x 40.60 = 2679.6 - The total amount paid by them
2/3 x 66 = 44 - The amount of people paying $50
44 x 50 = 2200 - The total amount paid by them
132 - 66 - 44 = 22 - The total amount of people paying $55.2
22 x 55.2 = 1214.4 - The total amount paid by them
1214.4+2200+2679.6+110= 6204 - Total money
