Question

Brie and Gillian were selling tickets to sports Night. Gillian sold about 6 adult tickets and 15 student tickets for a total of $48.00. Brie sold 8 adult tickets and 7 student tickets for a total of $38.00. What was the price of each ticket?

Answer 1

Explanation:

Given data

let adults be x

and student be y

so

6x+15y= 48-----------1

and

8x+7=38-----------2

solve eqn 1 and 2

6x+15y= 48-----------1X 8

8x+7=38-----------2X 6

48x

+15y= 40

48x+7y= 38

subtract

8y=2

y= 2/8

y= 1/4

y= $0.25

from 8x+7=38

put y= 0.25

8x+7(0.25)=38

8x+1.75= 38

8x=38-1.75

8x=36.25

x=36.25/8

x=$4.5
