4. Suppose that the company wishes to use a continuously-varying pricing system R = B + (P x Q), where B is the base price, P is the price increase coefficient, Q is the total consumption and R is the price per kWh. If the company uses a base price of 6.50, determine the value of P, up to 4 decimal places, so that the total amount due for all the customers will be the allowed amount of P 8,815.00. [2 pts.] Note that Total amount due = B E Qi -F P E Q?'
