Question

// Write the method determineTax. The method is sent the amount of the

// purchase and the tax rate. It returns a double value that is the

// amount of the tax.

// Note that the method determineTax does not print anything -- it

// just returns the value.

double m1 = determineTax(350.00, 0.06); // Michigan is 6%

double m2 = determineTax(79.99, 0.06);

double cal1 = determineTax(499.99, 0.0725); // California is 7.25%

System.out.printf("Here are the returned values: %.2f, %.2f, and %.2f ", m1, m2, cal1);

Explanation / Answer

DetermineTaxTest.java

public class DetermineTaxTest {

public static void main(String[] args) {

double m1 = determineTax(350.00, 0.06); // Michigan is 6%

double m2 = determineTax(79.99, 0.06);

double cal1 = determineTax(499.99, 0.0725); // California is 7.25%

System.out.printf("Here are the returned values: %.2f, %.2f, and %.2f ", m1, m2, cal1);

}

public static double determineTax(double amount, double percentage) {

return amount*percentage;

}

}
