2x = 8

Then divide by 2

X = 4

Answer: The percent of the total was spent on veterinarian bills is 27.70% ( approx).

Step-by-step explanation:

Given, In 2011, Americans spent approximately $50.9 billion on their pets.

i.e. Total amount they spent on pets = $50.9 billion

Amount spent for veterinarian bills.  = $14.1 billion was for veterinarian bills.

\dfrac{\text{Amount spent for veterinarian bills. }}{\text{Total amount they spent on pets}}\times100\\\\=\dfrac{14.1}{50.9}\times100\\\\=27.7013752456\approx27.70\%

Hence, the percent of the total was spent on veterinarian bills is 27.70% (approx).
