. A recent mining engineering graduate wants to purchase a new car in 5 years which presently costs \$ 40,000 but the price of the car is rising at an annual compound rate of 12%. If he makes semiannual deposits to an account which pays 16 % compounded semiannually, how large must these payments be?

Amount Req after 5 years = Current Price (1+i)5

Where i is inflation rate

= \$ 40,000 * (1+0.12)5

= \$ 40,000 * (1.12)5

= \$ 40,000 * 1.7623

= \$ 70,493.67

Thus FV of annuity shall be equal to \$ 70,493.67

Here Payments are semi nnual

FV of Annuity = Cash flows * [ (1+r)n - 1 ] / r

where r is int rate per six months & n is no. of six months

\$ 70,493.67 = Cash Flow * [ (1+0.08)10 - 1 ] / 0.08

= Cash Flow * [ (1.08)10 - 1 ] / 0.08

= Cash Flow * [ 2.1589 - 1 ] / 0.08

= Cash Flow * [ 1.1589 ] / 0.08

Cash Flow = 70,493.67 * 0.08 / 1.1589

= \$ 4,866.25

Pls cmment, if any further assistance is required.
