Question

Bella saved $100 per month for 8 months. At the end of eight months, she had a total of $879 in her savings account. What is Bella’s rate of return?

Answer 1

Bella's rate of return is 779%.

Step-by-step explanation:

To find Bella's rate of return, we can divide the total amount she had at the end of eight months ($879) by the amount she saved each month ($100).

This will give us the number of times her savings increased.

To calculate the rate of return, we subtract 1 from this value and convert it to a percentage:

Rate of return = ((Total amount / Amount saved) - 1) * 100

Rate of return = ((879 / 100) - 1) * 100

Rate of return = (8.79 - 1) * 100

Rate of return = 7.79 * 100

Rate of return = 779%

Answer 2

79

Step-by-step explanation:

This is because 8 times 100 is 800.

Then 879-800=79
