Suzette deposited $800 into a bank account earning simple interest of 2.5% each year. After 5 years, how much interest had her account earned?

Respuesta :

Answer:

[tex]\boxed {\boxed {\sf \$ 100.00}}[/tex]

Step-by-step explanation:

The formula for simple interest is

[tex]I=prt[/tex]

where p is the principal, r is the rate, and t is the time.

The principal, or initial amount is $800 and the time is 5 years The interest rate is 2.5%, but we must convert to a decimal.

Divide by 100 or move the decimal place two spots to the left.

  • 2.5/100=0.025       or          2.5 ⇒  0.25 ⇒ 0.025

Substitute the known values into the formula.

[tex]p= 800 \\r= 0.025 \\t= 5[/tex]

[tex]I= (800)(0.025)(5)[/tex]

Multiply.

[tex]I=20(5)\\I=100[/tex]

After 5 years, Suzette's account has earned $100.00
