Final answer:
Winston Enterprises needs to calculate the time needed to save $158.82 million at a 6 percent annual interest rate compounded monthly, saving $590,000 each month. We use the future value of an annuity formula for this purpose. The time frame can be calculated by solving for the number of monthly payments in the compound interest formula.
Step-by-step explanation:
The question concerns the length of time it will take for Winston Enterprises to save enough money to pay cash for a new factory expansion, given their monthly savings and an interest rate of 6 percent compounded monthly. To solve this problem, we apply the future value formula for compound interest. This is a typical business scenario where a firm is planning for expansion by investing in new equipment or facilities and making financial decisions based on its ability to fund such investments without seeking external financing.
To calculate the time frame for the savings to reach $158.82 million, we would use the formula for the future value of an annuity with monthly compounding interest: FV = P * [((1 + r)^n - 1) / r], where FV is the future value, P is the monthly payment, r is the monthly interest rate, and n is the number of payments. The solution would require finding the number of months (n) that satisfies the equation, given that P = $590,000, r = 0.06/12 per month, and FV = $158.82 million.
