Assignment Instructions
1. Write a program to calculate and output order subtotal amount, total sales tax amount, and order total amount. Ask the user to provide following information:
a. Price and quantities for 3 items
. Sales tax in % (e.g. 8.8% should be entered as 0.088)
2. Write a program that asks the user for the number of miles driven and the gallons of gas used. It should calculate the car’s MPG (Miles per Gallon) and display the result.
3. Write a program to calculate and output the present investment amount given the future expected earnings, interest rate, and timeframe to hold the investment amount. Ask the user to provide following information:
a. Future expected earnings i.e. FV
. Expected annual interest rate i.e.
c. Timeframe in years i.e. n
For example, how much do you need to invest today (i.e. Present Value PV) at 10% (i.e. interest rate r) compounded annually in order to have $1,000,000 (i.e. future value FV) 20 years (i.e. number of years, n) from today?
Use the following formula
XXXXXXXXXX
PV = FV * -----------------
XXXXXXXXXXr) n
4. Calculate and output monthly loan payment. Ask the user to provide following information:
a. the loan amount (P),
. APR i.e. Annual Percentage Rate (e.g. 5% should be entered as 0.05)
c. loan terms in number of months (n).
Use the formulas below to calculate and output monthly loan payment:
= APR in percentage / 12,
r * (1 + r) n
Monthly Payment (A) = P * ---------------------
(1 + r) n - 1
5. Write a program that calculates the total amount of a meal purchased at a restaurant. The program should ask the user to enter their name, the charge for the food, what percent tip, and 7 percent sales tax. Display each of these amounts and the final total amount along with the user name.
