-14a-5=-12
+5 +5
-14a=-7
Divide -7 by -14a
a=2
The correct answer is letter C
1/5 five being the denominator, because in math you must always simplify
Revenue, R = 130x
Profit, P = Revenue – Cost
P = R – C
P = 130x – 2950 + 6x + 0.1x^2
At P = 0
0 = -2950 + 136x +0.1x^2
X = 21.355, -1381.355
Therefore, manufacture greater than 21.355 items to make
profit.
