Question

a bike rental costs $2.50 per hour plus a fee for renting a helmet. the total cost of renting a bike for 2 hours (h) is $13. the total cost, y, is a function of the hours, x. what given information tells you the rate of change? a bike rental costs $2.50 per hour. what is the rate of change? rate of change: blank bike rentals $2.50 per hour (additional fee for helmet rental)

Explanation:

Step1: Understand rate of change

In a linear function \( y = mx + b \), the rate of change is the slope \( m \), representing the change in \( y \) per unit change in \( x \). Here, \( y \) is total cost, \( x \) is hours.

Step2: Identify rate of change info

The cost per hour (\$2.50) is the rate at which total cost changes with hours. So the rate of change is \$2.50 per hour.

Answer:

\( \$2.50 \) per hour (or \( 2.50 \) if just the numerical value with unit context)
