Question

An adult ticket to an exhibition cost $5 while a child ticket cost $2. If the number
of children going to the exhibition was 3 more than the number of adults and a total
amount of $20 was spent on the tickets, find the number of adults going to the
exhibition​

Answer 1

Step-by-step explanation:

let, the no. of adults be 'x'

no. of children = x+3

5x + 2(x+3) = $20

5x+2x+6 = $20

7x= $14

x= 2

x+3 =5

no. of adults = 2

no. of children = 5
