Solar Power Panel using C++ Assignment Solution


Solar Panel Installation

Description:

In this assignment, you will develop a C++ program that calculates the cost to replace all generators and solar panels for an energy business. Customers paying cash get a ten percent discount applied to the total cost of generators and solar panels. Customers financing the purchase incur a fifteen percent finance charge based on the total cost of the generator and solar panels. Generators cost $7500.00 each, and solar panels cost $500.00 each. The tax is 7.5% (.075).

Hints:

The total cost of equipment = cost per generator * number of generators purchased + cost per string trimmer * number of string trimmers purchased

Calculate the cost of paying cash or financing Calculate the tax

The average price per energy equipment = Total cost divided by the number of energy equipment purchased Use getline to get strings and cin to get numbers. See example below
