The equation y ̂=844.697x^2+3723.485x-13,650 models the annual profits of a new business, where x is the number of years since they opened.
use the equation to predict the annual profits, to the nearest dollar, 8 years after they opened.

The answer is $37,923

y = 844.697x^2 + 3723.485x - 13,650
x - number of years
y - the annual profit

If x = 8, the annual profit y is:
y = 844.697 * 8^2 + 3723.485 * 8 - 13,650
y = 844.697 * 64 + 29,787.88 - 13,650
y = 54,060.608 + 16,137.88
y = 37,922.728 ≈ 37,923
