Answer:
we need $7200 to earn $900 in 5 years.
Step-by-step explanation:
Simple Interest formula:
.......where p is principal, r is rate of interest, t is time
Using the formula:





Total number of pairs = 24 pairs.
Total cost of 24 pairs = $800 approximately.
Cost of each pair = 
Plugging values in the above formula, we get
Cost of each pair = 
If we divide 800 by 24, we get 33.33 approximately.
But in the given problem, estimated cost is given $28 per pair.
If we subtract 33.33-28, we get $5.33.
So, the estimated cost is $5.33 each pair less than the actual cost of each pair.
Therefore, $28 per pair is not a good estimate of the price.
