You just have to use the squares one to factor this and this is what I got.
Answer:
$347,600
Step-by-step explanation:
There is fixed startup cost of 242,000 no matter how many units they product.
Also, each unit costs 6 to produce, so to produce 17,600 items, it's going to cost:
17,600 * 6 = 105,600
Along with this the fixed startup cost of 242,000, would make total cost:
Total cost = 242,000 + 105,600 = $347,600
Answer: Last option.
Step-by-step explanation:
The equation of the line in slope-intercept form is:

Where m is the slope and b the intersection with the y-axis.
You can observe in the graph that the line passes through the origin, then:

Choose two points of the line and calculate the slope with:

Points: (2,3) and (-2,-3)
Substitute values, then the slope is:

Substituting "m" and "b" into
, you get that the equation is:

This can be written as:

I think it would be easiest to solve for x in this system of equations if you did so by elimination:
Start by finding the least common multiple of 3 and 2 to make the Ys cancel:
4x-6y=-54
-9x+6y=69
_________
-5x=15
x=-3 - answer B
