The answer is <u>$14,765</u> because six percent of 18000 is One thousand eighty, and when it is multiplied by three(3 years) it becomes 3240 dollars. So you would just find the difference after that.
What you do is multiply regularly then add the negative sign, but if your multiplying 2 negatives it’s a positive answer. I cant help with the Fractions caz I’m not good at them lol .
