方程式(英文)
(1) Let the number of student tickets sold be x Then the number of *** tickets sold = 1200 - x Total revenue = 30x + 75(1200 - x) = 72000 30x + 90000 - 75x = 72000 18000 = 45x x = 400 400 student tickets have been sold. (2) Let John's saving be $x The the saving of his sister = $(x - 300) They have in total x + x - 300 = $(2x - 300) x - 450 = (2/5)(x - 300 + 450) 5(x - 450) = 2(x + 150) 5x - 2250 = 2x + 300 3x = 2550 x = 850 They have in total = $(1700 - 300) = $1400 (3) After o hours
David would have travelled 15 * 2 = 30km Alice would have travelled 2y km The original distance beeen David and Alice was = 100km After o hours their distance will be | 100 + 30 - 2y | = | 130 - 2y | km
