Answer and Explanation:
The computation is shown below:
The formula is
= Amount ÷ (1 + interest rate)^number of years
a) Rate = 11%
Value of $140 in 1 year = $140 ÷ (1 + 11%) = $126.13
Value of $240 in 5 years = $240 ÷ (1 + 11%)^5 = $142.43
Value of $350 in 10 years = $350 ÷ (1 + 11%)^10 = $123.26
Now Ranking
Opotion 2 > Option 3 > Option 1
b) Rate = 1%
Value of $140 in 1 year = $140 ÷ (1 + 1%) = $138.61
Value of $240 in 5 years = $240 ÷ (1 + 1%)^5 = $228.35
Value of $350 in 10 years = $350 ÷ (1 + 1%)^10 = $316.85
Now Ranking
Option 3 > Option 2 > Option 1
c) Rate = 20%
Value of $140 in 1 year = $140 ÷ (1 + 20%) = $116.67
Value of $240 in 5 years = $240 ÷ (1 + 20%)^5 = $96.45
Value of $350 in 10 years = $350 ÷ (1 + 20%)^10 = $56.53
Now Ranking
Option 1 > Option 2 > Option 3
