Atheater sells adult tickets for $8.00 and children's tickets for $5.50. sally bought some of each kind (not the same number) and paid a total of $78.50. which equation represents this situation?

8x + 5.50y = 78.50

Step-by-step explanation:

Let Sally bought adult tickets = x

and children tickets = y

since, value of the adult tickets is $8.00 per ticket so total cost of x tickets = 8x

since value of children's tickets is $5.50 per ticket so total cost of y tickets = 5.50y

so total cost of the adult and children's tickets = 8x + 5.50y

Sally paid a total of $78.50. therefore, equation will be

8x + 5.50y = $78.50

Answer is 8x + 5.50y = $78.50
