Find the total number of tickets

Question

An amusement park sells child and adult tickets at a ratio of 8 to 1. On Saturday they sold 147 more child tickets than adult tickets. How many tickets did the amusement park sell on Saturday?

Answer 1

Let c = the number of child tickets

Let a = the number of adult tickets

c/a = 8/1      c = 8a

a + 147 = c

a + 147 = 8a

147 = 7a

21 = a

c/21 = 8

c = 168

a+c = 189 tickets on Saturday
