Question

Q2A. Write a function called travelCost, that returns the price to be paid by a customer purchasing tickets. The function takes 3 input arguments:

ticketPrice, the cost of a single ticket, before the 13% Ontario Harmonized Sales Tax(HST).

passengers, the number of passengers for this purchase;

hstExempt: if true, this indicates this fare purchase should not be charged the 13% HST.

For examples, a silent purchasing tickets on behalf of three HST-exempt passengers paying $40.45 per fare would owe $121.35 (ie 3*$40.45); if the purchase was not HST-exempt, the purchaser would pay $137.13 (ie. 3*$40.45*1.13).

Explanation / Answer

//Java code to calculate travelCost

import java.text.DecimalFormat;

public static double travelCost(double ticketPrice , int passengers , boolean hasExempt) {
   DecimalFormat df = new DecimalFormat("#.##");
if(hasExempt) {   
   // if hasExempt is true , the code will not impose HST   
   return Double.valueOf(df.format(ticketPrice*passengers));
}
return Double.valueOf(df.format(ticketPrice*passengers*1.13)) ;
}
