Vishal deposits $65 into a new savings account. The account earns 7.5% interest per year. No money is added or removed
Black_prince [1.1K]

Answer:

$79.23 After 3 years

Step-by-step explanation:

Use I P R T it's a method for simple interest

I = Interest

P = Amount of money

R = Percent in decimal

T = Time in years

Answer:

I = x (we dont know yet)

P = $65

R = 7.5% = 0.075

T = 3 years

Steps:

1. Set up your numbers with the method I P R T.

2. $65 will be your amount of money.

3. 7.5% needs to be converted because you will need to multiply later on in the problem. Simply move 2 places to the left to convert your percent into a decimal.

4. They want to know the total amount of money in his account at the end of 3 years. So 3 years will be your time in years.

5. After setting up your problem you need to multiply your Amount of money x percent as decimal x time in years.

65(0.075)(3)=14.63\\ Interest\\

6. After you find your interest you need to add your amount of money + interest.

65 + 14.63 = 79.23 Money after 3 years

hope this helped
