(a) Suppose the gasoline costs 99 cents$0.99 and the distance is 280 miles.
Use the functional notation, the cost of operation is,
$C\left(0.99,280\right)=\frac{0.99×280}{32}dollars$
Therefore, the cost is,
$C\left(0.99,280\right)=\frac{0.99×280}{32}\phantom{\rule{0ex}{0ex}}=\frac{277.2}{32}\phantom{\rule{0ex}{0ex}}\approx 8.66$
b)
Calculate C(1.02,178).
$C\left(1.02,178\right)=\frac{1.02×178}{32}\phantom{\rule{0ex}{0ex}}=\frac{181.56}{23}\phantom{\rule{0ex}{0ex}}\approx 5.67$
This represents the cost of driving 178 miles if gas costs S1.02 per gallon.
