QuestionJerome wants to rent a rowboat to go fishing at the lake. The cost of the rental can be represented by the equation $y=18 x$, where $x$ is the number of hours the boat is rented for, and $y$ is the total cost.
What is the cost per hour for renting the boat? There is no cost per hour, because the value for $b$ in the slope-intercept form of the equation $y=m \boldsymbol{x}+\boldsymbol{b}$ equals 0 . It costs $\$ 18$ to rent the boat all day. Renting the boat costs $\$ 0.18$ per hour. The cost per hour can't be determined without determining the number of hours it is used. Renting the boat costs $\$ 18$ per hour.
