Answer:
Check the calculation below.
Explanation:
a) Amount in account after 3 years:
= $1,000 (1+ 0.03)5 + $1,000 (1+ 0.03)4+ $1,000 (1+ 0.03)3 + $1,000 (1+ 0.03)2 + $1,000 (1+ 0.03)
= $1,159.27 + 1,125.51 + 1,092.73 + 1,060.90 + 1,030
= $5,468.40
b) Calculation of amount of payment:
Let the amount of each of two payment be "P".
Now, $4,000 = P (1 + 0.015)3 + P (1 + 0.015)2
or,$4,000 = 1.0457 P + 1.0302 P
or, P = $4,000 / 2.0759
or, P = 1,927 (Approx)
