Question

Jessica has an account with a credit union. Her account earns 2.6% simple interest yearly. Exactly a year and a half ago, she opened her account with $900.

How much interest has she earned so far?

Answer 1

35.1

(2.6*900*1.5)/100

Answer 2

$35.1

Explanation:

2.6% of 900 = 23.4

Since it's a year and a half you might want to divide by two.

2.6/2 = 1.3

1.3% of 900 = 11.7

add them up,

23.4 + 11.7 = 35.1

It's asking for how much she EARNED not HAS in her bank account in 1.5 years. So include what she earned with interest, do not include the 900 dollars because she didn't earn it with interest, she already had that.
