The cost of renting a truck for one day is $19.95 and has a rate of $0.50 per mile.
We can write a function rule to model the cost of renting a truck for one day.
[tex]y=0.50x+19.95[/tex]Where x is the number of miles and y is the corresponding cost of renting.
Now we can find the cost of renting for traveling 73 miles.
Substitute x = 73 into the function.
[tex]\begin{gathered} y=0.50(73)+19.95 \\ y=36.5+19.95 \\ y=\$56.45 \end{gathered}[/tex]Therefore, the cost of renting the truck for one day and 73 miles will be $56.45
