Answer:$7,200
Quantities that changed in the problem are
1. The value of the coin
2. The time it took to appreciate to that value
Step-by-step explanation:
Current value = $5,400
Increase in value (monthly) = $30
In 5 years time, the value would increase by
(12*5) * $30 = $1800
Value in five years = current value + increase in value
Value in five years = $5400 + $1800
Value in five years = $7,200
