Answer with Step-by-step explanation:
Amount in Bonnie's account initially=$ 70
The formula for simple interest=
Where P is the principal amount

and T is the time
Here, P=70,R=4.5,T=3
Interest=
= $ 9.45
Hence, Total amount in his savings account after 3 years= $(70+9.45)
= $ 79.45
Hence, correct option is:
