Question

[(Background information)Ms. Jackson wants to rent an oversize truck for a week. It will cost the weekly fee plus $0.60 per mile driven. Let m= the number of miles Ms. Jackson drives during the week. Use this information to answer the question] Evaluate the expression to find out how much she will pay if she drives 100 miles.[(Week-535)(Day-170)]

Answer 1

Let y be the cost per week of the rent for the oversized car, since there is a cost of $0.60 per mile driven, we can write

$y=0.60x+535$

where x represents the miles driven and $535 is the weekly fee form the given table.

Now, we need the cost per week when x=100 miles. Then, by substituting this values into our function, we have

$\begin{gathered} y=0.60(100)+535 \\ \end{gathered}$

which gives

$\begin{gathered} y=60+535 \\ y=595 \end{gathered}$

Hence, after 100 miles, she will pay $595 in one week.
