<u><em>DO NOT FORGET TO ADD THE TOTAL COST</em></u>
28.00 + (28.00 * .06) = 29.68

Answer:
The Y intercept is -5 and the slope is -5/2
The answer is $37,923
<span>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 = </span>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
