Answer :
The equation that represents the balance in the account after 15 years is : A = 5000(1 +0.018)^15.
Using this formula
A = P (1 + r)^t
Where:
A=Amount=?
Principal=$5,000
r=Interest rate=1.8% or 0.018
t=time=15 year
Let plug in the formula
A=5000(1 + 0.018)^15
A=5000(1.018)^15
A=5000(1.30682270)
A= $6,534.11
Inconclusion the he equation that represents the balance in the account after 15 years is : A = 5000(1 +0.018)^15.
