Jerry starts with $1400 in a college savings account. His account earns interest at a rate of 2.7%

tigry1 [53]

Answer: There will be $ 1687.02 in the account after 7 years.

Step-by-step explanation:

Formula to find the accumulated amount (A) in account on principal amount (P) with rate of interest (r) in 't' years is given by :-

$A=P(1+r)^t$

As per given, P = $1400

r= 2.7% = 0.027

t= 7 years

Then,

$A= 1400(1+0.027)^7\\\\= 1400(1.027)^7\\\\= 1400(1.2050168)\\\\= 1400(1.2050168)\approx1687.02$

Hence, there will be $ 1687.02 in the account after 7 years.
