Answer:

C = 7x + 5y

Step-by-step explanation:

Algebraic Expressions

Erica purchased tickets for a movie. It's given each adult ticket cost $7 and each youth ticket cost $5.

If each adult ticket cost $7 and she bought x tickets, then she spent 7x dollars on adult tickets.

Similarly, if each youth ticket cost $5 and she bought y tickets, then she spent 5y dollars on youth tickets.

The total cost C is the sum of the individual costs, thus:

C = 7x + 5y

There are $7 for EACH person so u multiply. Same as $5 and y. (So 7x+5y)
