Program #$1$

Sales Tax

Write a program that will ask the user to enter the amount of a purchase. The program should then compute the state and county sales tax. Assume the

state sales tax is $4$ percent and the county sales tax is $2$ percent. The program should display the amount of the purchase, the state sales tax,

the county sales tax, the total sales tax, and the total of the sale $($which is the sum of the amount of purchase plus the total sales tax$).$

Hint: use the value $0\mathrm{.}02$ to represent $2$ percent, and $0\mathrm{.}04$ to represent $4$ percent.

TEST CASE: Demonstrate your program by using a value of $$147\mathrm{.}53$ for the purchase.
