Final answer:
To find the annual deposit that XYZ Inc. needs to make for the last five years at a 13% interest rate to accumulate P8,000,000.00, the future value of an annuity formula is used and solved for PMT.
Step-by-step explanation:
To determine the annual deposit XYZ Inc. must make for the last 5 years to accumulate P8,000,000.00 at a 13% interest rate, we can use the future value of an annuity formula. The formula is:
FV = PMT × { [(1 + r)n - 1] / r }
Where FV is the future value, PMT is the payment per period, r is the interest rate per period, and n is the number of periods.
From the question, FV is P8,000,000.00, r is 13% (or 0.13) compounded annually, and n is 5 years.
Thus, the formula we'll use to solve for PMT is:
PMT = FV / { [(1 + r)n - 1] / r }
Plugging the values we get:
PMT = P8,000,000.00 / { [(1 + 0.13)5 - 1] / 0.13 }
After calculating, we find the PMT, which is the annual deposit required for the next 5 years.
