To discourage excess consumption, an electric company charges its customers at a lower rate,P$3\mathrm{.}00,$ for each of the first $250$ kilowatt hours, and a higher rate of P$4\mathrm{.}50$ for each additional kilowatt hour. In addition, a $5\%$ tax is added to the final bill. Write a program to calculate

electric bills given the number of kilowatt$-$hours consumed as input. Use two functions: one to compute the amount without the tax and one to compute the total amount due.The definition for the second function should include a call to the first function.The following are the function declarations.float initialBill$($int kwh$)$;float finalBill$($int kwh$)$;Test the function inside main$().$ Write the complete program.
