Question $1(45$ points$)$

Write a program that computes a customer's monthly electricity bill.The bill includes a $10($Riyals$)$ monthly fee of meter, $15\%$ added value rate on the total consumption cost, and plus the cost of electricity consumption per kilowatt$/$hour based on the New Electricity Tariffs for all categories of consumption.

The program asks the user to input customer's name, the bill actual number of days, amount of electricity consumption, and then the total cost of electricity consumption is calculated based on the following Consumption categories.

$\backslash$table$[[$#$,$Consumption categories $($per month$),($Halalah $/$ kwh$)],[1,1$ to $6000,18],[2,$More than $6000,30]]$

And by the following formulas $($In case consumption exceeds consumption of first category$)$:

Consumption of the first category $=$ Actual number of days $**\frac{6000}{30}$

Consumption of the second category $=$ Amount of electricity consumption $-$ Consumption of the first category

Total consumption cost $=$ Consumption of the first category $**\frac{18}{100}+$ Consumption for the second category $**\frac{30}{100}$

Tax $=$ Total consumption cost $**$ Added value rate

Bill amount $=$ Monthly fee of meter $+$ Total consumption cost $+$ Tax

Note:

In case consumption does not exceed that of first category, then the bill will be based on $18$halal$\frac{h}{k}wh$ only.

Following is an example that explains how to calculate the cost of electricity consumption for a person who consumed $7000$ kwh in $27$ days.

$\backslash$table$[[$category$,$Consumption $(kwh),($Halalah $/$ kwh$),$Total amount$],[1,5400,18,972],[2,1600,30,480]]$

Total SAR $1452$ withot added value and montly meter service
