Dave sold 40 tickets for a concert. He sold x tickets at 2$ each and y tickets at 3 each. he collected 88$. write down two equations connecting x and y

Question

solve these two equations to find how many of each kind of ticket he sold

Answer 1

use total tickets:    x + y = 40

 

use prices:           2x + 3y = 88

Answer 2

Based on Sherry's answer, x = 40 - y

 

Substitute 40-y for x in the 2nd equation

 

2(40-y) + 3y = 88

80 - 2y + 3y = 88

-2y + 3y = 8

y = 8

x = 32
