Answer:
B
Step-by-step explanation:
There are two digits before the decimal
I. is false.
II. is true.
III. is false.
Only II. is true, so answer is choice D.
A. It is -6<b<10 so there are open circles at -6 and 10 with rays going off in opposite directions with a space in the middle
4x+ 20 = 3x + 55 (vertical angles)
4x - 3x = 55 - 20
x = 35
Answer:
a) C(x) = 125300 + 450x
b) R(x) = 800x
c) P(x) = 350x - 125300
d) Profit of $14,700
e) 358 computers
Step-by-step explanation:
The fixed costs are $125,300, and the variable costs are $450 per unit.
The revenue from each computer is $800.
a) The total cost C(x) of producing x computers.
C(x) = 125300 + 450x
b) The total revenue R(x) from the sale of x computers.
R(x) = 800x
c) The total profit P(x) from the production of and sale of x computers.
P(x) = R(x) - C(x).
P(x) = 800x - (125300 + 450x) = 800x - 125300 - 450x = 350x - 125300
P(x) = 350x - 125300
d) The profit or loss from the production and sale of 400 computers
P(400) = 350.400 - 125300 = 140000 - 125300 = 14700
Profit of $14,700
e) The break-even point.
R(x) = C(x)
800x = 125300 + 450x
350x = 125300
x = 125300/350
x = 358
The break even point is 358 computers.
