Answer:
A) x = 2, x = 7
Step-by-step explanation:
x^2 + 14 = 9x
Subtract 9x from each side
x^2-9x + 14 = 9x-9x
x^2-9x + 14 = 0
What 2 numbers multiply to 14 and add to -9
-7*-2 = 14
-7+-2 = -9
(x-7)(x-2) = 0
Using the zero product property
x-7 = 0 x-2 =0
x=7 x=2

The cost of a single shot is
.78 +.52 +.96 = 2.26
they charge 25 a shot

there is a profit of 22.74 per shot
22.74 * 167 =3797.58
They make $3797.58
