Question

A carnival charges $10 for admission and $1.25 for each ride. Jennifer has $17.50 to spend on admission and rides, so the equation 10 + 1.25r = 17.50 can be used to find the number of rides, r, she can ride. How many rides can she ride?

Answer 1

Jennifer can ride 6 rides.

Step-by-step explanation:

To find the number of rides Jennifer can ride, we need to solve the equation 10 + 1.25r = 17.50 for r.

Step 1: Subtract 10 from both sides of the equation:

1.25r = 17.50 - 10

Step 2: Simplify the right side of the equation:

1.25r = 7.50

Step 3: Divide both sides of the equation by 1.25:

r = 7.50 / 1.25

Step 4: Calculate the division:

r = 6

Therefore, Jennifer can ride 6 rides.
