A car that gets 32 miles per gallon: The cost C of operating a certain car that gets 32 miles per gallon is a function of the price g, in dollars per gallon, of gasoline and the distance d, in miles, that you drive. The formula for C = C(g, d) is C = gd/32 dollars.

a. Use functional notation to express the cost of operation if gasoline costs 98 cents per gallon and you drive 230 miles. Calculate the cost.

b. CalculateC(1.03, 172) and explain the meaning of the number you have calculated.
