Answer:The correct formula should be I= 600(0.07)(2). Juanita made a very common error, she didn’t put the percentage of interest in decimal form; or she didn’t put the percent sign on it so we know to put it in decimal form. Her error will make a big difference; with using her calculations the answer would be $8,400. With the correct formula the answer is $84.

Hope this help!🙂
