The domestic tariff charged by Sabah Electricity Sdn Bhd (SESB) is given in Table 1. Based on the tariff, write a C++ program that can do the following: a. Tell the user to input the monthly usage (in kWh) from January to December. b. Calculate the consumption, discount, tax, and bill in RM for each month. - For consumption of less than or equal to RM600 per month, a 10% discount is given. For consumption of more than RM600 per month, a 6% service tax is imposed. c. Display the output as depicted in Figure 1. Format the values to two decimal points. Table 1 Tariff Category Unit Rates For the first 100 (1-100kWh) per month Sen/kWh 17.5 For the next 100 (101-200kWh) per month Sen/kWh 18.5 For the next 100 (201-300kWh) per month Sen/kWh 33.0 For the next 200 (301-500kWh) per month For the next 500 (501-1000kWh) per month Sen/kWh 44.5 Sen/kWh 45.0 For the next kWh (1001kWh onwards) per month Sen/kWh 47.0 Month Usage(kWh) Consumption(RM) 10% Discount(RM) 6% Tax(RM) Bill(RM) Jan 100 17.50 1.75 0.00 15.75 Feb 200 36.00 3.60 0.00 32.40 March 300 69.00 6.90 0.00 62.10 April 2000 849.00 0.00 50.94 899.94 May Dec Figure 1
