Complete question :
Admission rate at local aquarium :
Ticket ________ Price
Children _______ $9
Adult __________ $15
Mr.Reilly spent $90 on tickets to the aquarium. Write an equation in standard form to represent the situation
Answer:
y = 6 - (9/15)x
Explanation:
The amount spent = [(rate of children ticket * number of children ticket obtained) * rate of adult ticket * number of adult ticket purchases)]
Let :
number of chikdren ticket = x
Number of adult ticket = y
(15 * y) + (9 * x) = 90
15y + 9x = 90
15y = 90 - 9x
Divide through by 15
y = 6 - (9/15)x
