Question

The entry fee to the fair is $4.00. Each ride requires a ticket that costs $0.50. Heidi spent a total of $12.00. Write an equation to find the number of rides Heidi can go on. (Use the variable r for the number of rides.)

a) 4r = 12
b) 4 + 0.50r = 12
c) 4 + 12r = 0.50
d) 0.50r = 12 - 4

Answer 1

To find the number of rides, subtract the entry fee from the total amount spent and divide the result by the cost of each ride ticket. Heidi can go on 16 rides.

Step-by-step explanation:

To find the number of rides Heidi can go on, we need to subtract the entry fee from the total amount she spent and then divide the result by the cost of each ride ticket:

Step 1: Subtract the entry fee from the total amount spent: $12.00 - $4.00 = $8.00

Step 2: Divide the remaining amount by the cost of each ride ticket: $8.00 ÷ $0.50 = 16

Heidi can go on 16 rides.
