so would the answer be 97.37

writeacher is the answer 136.31

Hmmm. when you use the word interest, you have to specify what that is: For instance, if 9 percent is annual interest, or if 9 percent is for 7 months (which would be almost 17 percent annual).

If your interest fee is 9 percent annual, but paid at the end of 7 months in total, then interest=7/12* 2596.4*(.09)=136.31

You have to be very precise in your problem statement, as I assure you the question as written can be interpreted as something different.

thank you

To calculate the total interest, you can use the formula:

Total Interest = Principal * Interest Rate * Time

Here's how to calculate the total interest:

Step 1: Convert the interest rate from a percentage to a decimal.
Interest Rate = 9% = 0.09

Step 2: Plug in the values into the formula.
Principal = $2596.40
Time = 7 months

Total Interest = $2596.40 * 0.09 * 7

Step 3: Calculate the result.

Total Interest = $2057.76

Therefore, the correct answer is $233.68, as you chose. So, well done!
