Question

Renting snow skis costs $15 per hour plus a $10 usage fee. Create a step function that models the cost of snow skis in terms of the number of hours the snow skis were rented. Graph your step function from t = 0 hours to t= 10 hours. Then use your model to determine the cost for the snow skis if you were skiing for 4.5 hours.

Answer 1

The cost for the snow skis for 4.5 hours is $ 77.5.

Explanation:

Since renting snow skis costs $ 15 per hour plus a $ 10 usage fee, to create a step function that models the cost of snow skis in terms of the number of hours the snow skis were rented and determine the cost for the snow skis if you were skiing for 4.5 hours the following calculation must be performed:

10 + (15X) = Cost per hour

10 + 15 x 4.5 = X

10 + 67.5 = X

77.5 = X

Therefore, the cost for the snow skis for 4.5 hours is $ 77.5.
