The formula for accumulated value of something with a percentage growth p and years x is:

V(x) = Initial Value * (1 + p/100)^x

Set up our growth equation where 8% = 0.08 and V(y) for the value at time x and x = 2020 - 1970 = 50, we have:

V(x) = 100 * (1 + 8/100)^50

V(x) = 100 * (1.08)^50

V(x) = 100 * 46.9016125132

V(x) =

**4690.16**
