Question 1207048: A farmer has just bought a new tractor for NAD800 000. He has to replace the
tractor in 5 years’ time, when its trade-in value will be NAD200 000. The
replacement cost of the tractor is expected to increase by 8% per annum.
2. The farmer wants to replace his present tractor with a new one in 5 years’ time.
The farmer wants to pay cash for the new tractor, after trading in his present
tractor for NAD200 000. How much will he need to pay?
(5 MARKS)
3. One month after purchasing his present tractor, the farmer deposited x NAD
into an account that pays interest at the rate of 12% p.a compounded monthly.
He continued to deposit the same amount at the end of each month for a total
of 60 months. At the end of 60 months, he has exactly the amount that is needed
to purchase a new tractor, after he trades in his present tractor. Calculates the
value of x.
(5 MARKS)
4. Suppose that 12 months after the purchase of the present tractor and every 12
months thereafter, he withdraws NAD5 000 from his account, to pay for
maintenance of the tractor. If he makes 5 such withdrawals, what will the new
monthly deposit be?
