The above are used in the attached excel file to calculate the interest rate.
The interest rate is calculated using the following simple excel rate function in the attache excel file:
=RATE(npr,pmt,-pv)
Where;
pv = Present value = Equipment cash cost = $189,200
pmt = Yearly payment = $46,000
npr = Number of years = 6
Using the function in the attached excel file, we obtained 12%. Therefore, the correct option is b) 12%.
