tickets cost 10$ for adults and 6$ for children. there was total of 90 tickets sold and a total of 800$ collected, how many each type of ticket were purchased

Question

let x=#of adult tickets purchased and y=# of children tickets purchased

Answer 1

Let x = number of adult tickets purchased

Let y = number of children's tickets purchased

 

x+y = 90               (1)

10x + 6y = 800      (2)

 

You have two equations with two unknowns,  can you solve this system for x and y?
