Answer:
the total cost of 200 copies at a rate of 0.25 cents a copy with a $30 are the same when 233 copies are ordered at 0.15 cents per copy plus the $50 set up fee.
Step-by-step explanation:
We can find the answer to this by comparing the prices:
200 x $0.25 + $35 = $85 this can be written in function notation as
f(x) = 200x + 35
If X = .25 then:
f(0.25) = 200(0.25) + 35 = 85
Using this same equation we can see that
f(0.15) = 200(0.15) + 50 = 80
Now we simply need to divide the difference between the two amounts by 0.15 to find the answer: 5/0.15 = 33.3--
The answer represented by an inequality is 200 < x < 233.
Also notice how the first has a lower y intercept but a steeper slope, and the second has a higher y intercept but less steep slope.
