Write a program that asks the user to enter the number of hours for electric usage and calculates the charge according to the following:

a$.$ Regular charge is $$0\mathrm{.}01/$hour$.$

b$.$ Charge for hours over $100$ is $$0\mathrm{.}03/$hour Declare charge as double. Make sure charge is formatted to two digits after the decimal point.

e$.$g$.$ If usage is $50$ hours, charge is $50$ cents.

e$.$g$.$ If usage is $100$ hours, charge is $$1.$

e$.$g$.$ If usage is $101$ hours, charge is $$1\mathrm{.}03.$

e$.$g$.$ If usage is $107$ hours, charge is $$1\mathrm{.}21$

e$.$g$.$If usage is $150$ hours, charge is $$2\mathrm{.}50.$
