Question

Arisia puts $500 into a savings account with an annual simple interest rate of 4.5%. If the interest rate stayed the same, how much money would be in Arisia’s account after 20 years?

Answer 1

She would have $10,450

Answer 2

Answer:

$112.5

Step-by-Step Explanation:

Step one:

given data

principal= $500

rate= 4.5= 0.045

time t= 5years

Step two:

the expression for the simple interest is given as A=P(1+rt)

the interest SI= final amount (A)- Principal(P)

Substituting we have

A=500(1+0.045*5)

A=500(1+0.225)

A=500(1.225)

A=612.5

the interest is 612.5-500

=$112.5
