The change in Microbiotics' total monthly profits on a present value basis if credit is offered to all customers is $2,386.61 positive.
The calculation of the present value involves the discounting of the interest rate from the future cash flows.
The present value can be computed using the present value table or an online financial calculator.
Price per carton = $160
Cost per carton = $95
Profit per carton = $65 ($160 - $95)
Total profit for 1,110 cartons = $72,150 ($65 x 1,110)
Total profit for 1,170 cartons = $76,050 ($65 x 1,170)
Cost of credit = $760.50 ($76,050 x 1%)
Change in profit = $75,289.50 ($76,050 - $760.50)
Discount factor of 1% = 0.990
Present value of $75,289.50 at 1% in a month's time = $74,536.61 ($75,289.50 x 0.990)
Thus, the change in Microbiotics' total monthly profits on a present value basis if credit is offered to all customers is $2,386.61 positive ($74,536.61 - $72,150).
