Using loops and condition statements together, Write a program that calculate the cost of energy for energy units restricted between 0 to 500 kWh for an amount less than $6 000.00 for any Zimbabwean resident customer and any amount and unlimited number of units for a foreign resident customer buying from outside Zimbabwe at a rate of $90.00 to one USD. The tariffs are as follows:
• 0 to 50 kWh cost $2.25
• Above 50 kWh to 100 kWh cost $4.51 / kWh
• Above 100kWh to 200 kWh cost $7.89 / kWh
• Above 200kWh to 300 kWh cost $11.25 / kWh
• Above 300kWh to 400 kWh cost $12.94 / kWh
• Above 400 kWh cost $13.50 / kWh
