A customer in a store is purchasing three items. Write a program that asks for the price of each item, then displays the subtotal of the sale, the amount of sales tax, and the total. Assume the sales tax is $7$ percent.

The data type input from the user is float.

Once the user inputs the prices for the three items, your program will compute subtotal, the tax, and the total. The subtotal is the sum of total of the prices of the three items. The tax is computed based on the sales tax of $7$ percent. The total is the subtotal plus tax.
