Hello!
We will add up 0.046 of our number each year for four years as seen below.
1600(0.046)=73.6
1600+73.6=1673.6
1673.6(0.046)≈76.99
1673.6+76.99=1750.59
1750.59(0.046)≈80.53
1750.59+80.53=1831.12
1831.12(0.046)≈84.23
1831.12+84.23=1915.35
Therefore, you will have about $1,915.35 in your account after 4 years.
I hope this helps!
