5x(x - 3) = 2
5x(x) - 5x(3) = 2
5x² - 15x = 2
5x² - 15x - 2 = 0
x = -(-15) ± √((-15)² - 4(5)(-2))
2(5)
x = 15 ± √(225 + 40)
10
x = 15 ± √(265)
10
x = 1.5 ± √(265)
x = 1.5 + √(265) or x = 1.5 - √(265)

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
