Question

Bert is planning to open a savings account that earns 1.6% simple interest yearly. He wants to earn exactly $240 in interest after 3 years. How much money should he deposit?
A. $50
B. $500
C. $3,840
D. $5,000

Answer 1

Answer:

D. $5,000

Step-by-step explanation:

The amount of money he should deposit is the principal.

The principal P can be gotten by

P = 100 I /RT

Where

I = interest

R = rate

T = Time

Given

I = $240

R = 1.6%

T = 3 yrs

P = 100 x 240 /1.6 x 3

Multiply through

= 24000/4.8

= $5000
