Question

Need help with this!!!

Answer 1

Answer:

$9

Step-by-step explanation

interest = principal * interest rate * length.

so:

answer = (90) * (.1) * (1)

Answer is $9.

Another way of saying it:

You've got $90. You make 10% interest in 1 year if you put it in an account. What do you make? Well, what's 10% of $90? Divide 90 by 10. The answer is $9.

Hope this helps. Let me know if you have questions.
