A boat costs $19,700 and decreases in value by 11% per year. How much will the boat be worth after 3 years?

Find 11% of $19,700 first. To do this, multiply $19,700 by 0.11.

Once you do that (because you still have to do the work), multiply the answer by 0.11. After that, multiply the answer by 0.11. This is your answer. So basically:

19,700 x 0.11 = a

a x 0.11 = b

b x 0.11 = Your Answer.

13,887.8893

19700*0.89=A

A*0.89=B

B*0.89=13,887.8893
