Question

A company charges a one-time fee of $5 plus$12 per day to rent snowshoes. Write anexpression that represents the cost (in dollars)to rent the snowshoes for d days. How muchdoes a 4-day rental cost?

Answer 1

Answer:

$y=\operatorname{\ }\text{53}$

Step-by-step explanation:

This situation is represented by a linear function, remember that a line is represented by the following equation by the slope-intercept form:

$\begin{gathered} y=mx+b \\ where, \\ m=\text{ rate of change or rate per day} \\ b=\text{ initial fee} \end{gathered}$

Therefore, with the given information:

$y=12x+5$

Hence, substitute x=4 to determine the cost of a 4-day rental:

$\begin{gathered} y=12(4)+5 \\ y=\text{ \ 53} \end{gathered}$
