Question

For the first year of his car insurance policy, Tom pays $77 per month. As a reward for good driving, in the second year Tom's payments are reduced to $65 per month. What is the percentage decrease? Round your answer to the nearest whole percent.

Answer 1

77-65=12. The payments are reduced by $12. so you would do 12÷77=.1558441... which would be 15.58441...%. you would round this to 16%

the percentage decrease to the nearest whole percent is 16%.

Answer 2

Answer: Percentage decrease is by 15.58%.

Step-by-step explanation:

Since we have given that

Amount pays by Tom per month for the first year of his car insurance policy = $77

Amount pays by Tome per month for the second year of his car insurance policy = $65

We need to find the percentage decrease:

Percentage decrease is given by

$\dfrac{Difference}{original}\times 100\\\\=\dfrac{77-65}{77}\times 100\\\\=\dfrac{12}{77}\times 100\\\\=\dfrac{1200}{77}\\\\=15.58\%$

Hence, Percentage decrease is by 15.58%.
