Answer:
$184,687.98
Explanation:
assuming that silver dollars were issued in 1948 (actually no silver dollars were produced that year), your grandparents purchased them at $42. From 1948 to 2057 there are 109 years:
future value = present value x (1 + r)ⁿ
- present value =$42
- r = 8%
- n = 109 years
future value = $42 x 1.08¹⁰⁹ = $184,687.98
