(a) Let the total cost of renting a company truck = C
Let the drive unit per miles = d
Hence the formular = C(d) = $36.95 + 0.7d
(b) If the truck was driven for 45 miles, then the Cost of renting a company truck
[tex]\begin{gathered} C(d)\text{ = \$36.95 + 0.7(45)} \\ C(d)\text{ = \$36.95 + 31.5} \\ C(d)\text{ = \$68.45} \\ C(d)\text{ = \$68.5} \end{gathered}[/tex]
(c) Suppose you have a $100 budget the move, the
If the truck was driven with that budget then the further distance covered by the truck is
[tex]\begin{gathered} C(d)\text{ = \$36.95 + 0.7d} \\ \text{ \$100= \$36.95 + 0}.7d \\ \text{\$}100\text{ - \$36.95 = 0.7d} \\ \text{ \$63}.05\text{ = 0.7d} \\ \text{ d = }\frac{\text{ 63.05}}{7} \\ \text{ d = 90.007 miles} \\ \text{ d = 90miles (nearest miles)} \end{gathered}[/tex]
