Question:

The cost to go to the local fair can be displayed as the formula f=$7 + $0.50c, where f is the total cost and c is the number of ride tickets you want to purchase. If Kerri goes to the fair and plans to ride 9 rides, how much will the event cost her?


Answer:

f = total cost

c = number of ride tickets

f = $7 + $0.50c


cost for the fair and 9 rides

c = 9

f = $7 + $0.50c

f = $7 + $0.50*9

f = $7 + $4.50

f = $11.50


the final answer is: the fair (with 9 rides) will cost Kerri $11.50
