Consider the following formula,
C ( g . d ) = g d 32 d o l l a r s
Here, Cis the cost of operating a certain car with the price g in dollars and the distance d in miles.
(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 ( 0.99 , 280 ) = $ 0.99 × 280 32 d o l l a r s
Therefore, the cost is,
C ( 0.99 , 280 ) = $ 0.99 × 280 32 = $ 277.2 32 $ 8.66
b)
Calculate C(1.02,178).
C ( 1.02 , 178 ) = $ 1.02 × 178 32 = $ 181.56 23 $ 5.67
This represents the cost of driving 178 miles if gas costs S1.02 per gallon.
