Answer: $4,884.75
Step-by-step explanation:
The formula for determining simple interest is expressed as
I = PRT/100
Where
I represents interest paid on the amount deposited.
P represents the principal or amount deposited.
R represents interest rate
T represents the duration of the savings in years.
From the given information,
P = 4500
R = 2.85
T = 3 years
I = (4500 × 2.85 × 3)/100 = $384.75
The total amount that they will have in savings after 3 years is
4500 + 384.75 = $4884.75
