Monica purchased adult and youth tickets for the fair. She bought x adult tickets for $28 each and y youth tickets for $15. Write an expression that can be used to show the total cost, C, of all tickets.

C = (28 + 15)x
C = (28 + 15)(x + y)
C = 28x + 15y
C = 28y + 15x

She buy x amount of tickets for 28 dollars. x can take any number so you multiply x by 28 because you dont know what x is. The same with y and you add them up because y is a different ticket and not depended on x. Hope it's clear like this.
