Answer:
=$337.43
Explanation:
The value of each of the coins after 50 years is the future value after 50 years at their respective interest rate.
The formula for future value is FV = PV × (1+r)n
For the first coin at 5.2 percent,
Fv = 100 x ( 1 + 5.2/100 ) 50
Fv =100 x (1+ 0.052) 50
Fv = 100 x 12. 61208795
Fv = $1,261. 21
For the second coin at 5.7 percent,
Fv = 100 x (1 + 5.7 /100)50
Fv =100 x (1 + 0.057 )50
Fv = 100 x 15.98
Fv = 1, 598. 64
the difference in value will be
=$1598.64 - $1,261.21
=$337.43
