Follow-up Question

Hi, thanks for the soloution. Does this mean that the interest rate is already included in the monthly cost? Also in the picture I provided with the writing and the original answer to the question it shows the person answering the question mulitiplying and dividing the intertest rate and getting the answer $461.79. But when adding the interest to the montly payments it doesn't fit in with the 3 options already provided.
