Answer: $509

Step-by-step explanation:

Given : Gabe is getting married in three years and wants to save $20,000 for his wedding. He opens an account earning 6% interest, compounded monthly.

According to the given description, we have

A= $20,000 , r= 6%=0.06 , t= 3 years , n= 12 [1 yearn = 12 months]

Formula to find Periodic monthly deposit :-

$P=\dfrac{A\left(\dfrac{r}{n}\right)}{\left(1+\dfrac{r}{n}\right)^{\left(n\cdot t\right)}-1}$

Substitute given values in the above formula , we get

$P=\dfrac{20000\left(\dfrac{0.06}{12}\right)}{\left(1+\dfrac{0.06}{12}\right)^{\left(3\cdot12\right)}-1}\\\\=\dfrac{100}{1.19668052482-1}\\\\=\dfrac{100}{0.19668052482}=508.438749031\approx509$
