He would have $111,050.77 in the IRA.

Step-by-step explanation:

What we know:

The PMT is $1000

Rate of Interest (i in the formula) is 6.4% or 0.064 in decimal form

Number of periods (n) is 12

-

Equation (Future Value Formula):

FV = PMT ((1+i) ^n - 1) / i)

= 1000 ((1+0.064) ^12 - 1) / 0.064)

FV = 17,269.22 (rounded)

-

A stands for amount

T stands for time period which is 30

Finding IRA:

A = FV (1+i) ^t

= 17,269.22 (1+0.064) ^30

= $111,050.77
