Answer:
$716.64
Step-by-step explanation:
We will use the savings annuity formula
A(t)=d((1+r/n)n⋅t−1)r/n
and solve for d. In this case, A(5)=$50,000, r=0.06, and n=12 compounding periods per year. Substitute these values into the formula.
$50,000=d((1+0.06/12)5⋅12−1)0.06/12.
Simplify and solve for d.
$50,000$50,000 d=d(1.00560−1)0.005=69.7700305 d=$716.64
