Question

At the city meusum, child admission is $5.10 and the adult admission is $8.30. On Saturday, four times as many adult tickets were sold, for a total of sales of $9119.20. How many child tickets were sold that day?

Answer 1

238

Explanation:

child: $5.10

adult: $8.30

4 times as many adult as children

total: $9119.20

Let c = number of child tickets.

Let a = number of adult tickets.

5.1c + 8.30a = 9119.2

a = 4c

5.1c + 8.3(4c) = 9119.2

38.3c = 9119.2

c = 238.099

There must be a mistake with the numbers because the number of child tickets must be a whole number.
