The bowling alley charges a flat rate for a lane, plus a fee per shoe rental. Use the equation C = 15+ 3x to solve for the cost

Answer 1

In the provided equation \( C = 15 + 3x \):

• \( C \) represents the total cost.
• \( 15 \) is the flat rate for renting a bowling lane.
• \( 3x \) is the cost for shoe rentals, where \( x \) is the number of pairs of shoes rented.

To find the total cost, you can substitute different values for \( x \) (the number of shoe rentals) into the equation.

For example:

1. If no shoes are rented (\( x = 0 \)): \[ C = 15 + 3(0) = 15 \] The cost would be $15.

2. If one pair of shoes is rented (\( x = 1 \)): \[ C = 15 + 3(1) = 15 + 3 = 18 \] The cost would be $18.

3. If two pairs of shoes are rented (\( x = 2 \)): \[ C = 15 + 3(2) = 15 + 6 = 21 \] The cost would be $21.

4. If three pairs of shoes are rented (\( x = 3 \)): \[ C = 15 + 3(3) = 15 + 9 = 24 \] The cost would be $24.

You can keep substituting different values for \( x \) to find out the total cost based on the number of shoe rentals.
