Respuesta :

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

[tex]\dfrac{Difference}{original}\times 100\\\\=\dfrac{77-65}{77}\times 100\\\\=\dfrac{12}{77}\times 100\\\\=\dfrac{1200}{77}\\\\=15.58\%[/tex]

Hence, Percentage decrease is by 15.58%.
