Answer:
The intial fee is $5
The equation to represent this is: y=12x+5
12 is the cost per hour x=hours y=total cost
Step-by-step explanation:
77-41=36
36/3=12
12*6=72
77-72=5
C(x) = 400 + 20x - 0.2x²
c(30) = 400 + 20(30) - 0.2(30)²
= 400 + 600 - 0.2(900)
= 1000 - 180
= 820
It costs $820 when 30 radios are produced.
Marginal cost is how much it would cost to make one MORE of the same product so now we find how much it costs to produce 31 radios and compare the two.
c(31) = 400 + 20(31) - 0.2(31)²
= 400 + 620 - 0.2(961)
= 1020 - 192.2
= 827.8 or ≈828.
Now we find the difference which means we subtract the two.
828 - 820 = 8.
Your marginal cost is $8.
To compare we can also do 29 radios.
c(29) = 400 + 20(29) - 0.2(29)² = 811.8 or ≈812
820 - 812 = 8.
and
(f+g)(x) =
combining like terms gives you answer choice B
Answer:
D.
b = 175; which is the initial # of pages to start
Step-by-step explanation:
you can find the slope to find b or y-intercept (x=0) for equation
y=mx+b
to find m = (y2-y1)/(x2-x1)
(x1,y1) = (9, 100)
(x2, y2) = (15, 50)
m = (50-100) / (15-9) = -50/6 = -25/3
let use point (15, 50)
y=mx+b
50 = -25/3*x + b
50 = (-25/3)*(15) + b
50 = -125 + b
b = 175; which is the initial # of pages to start
