Suppose that the total cost of making and selling x widgets is c = 32x + 560 dollars. what is the meaning of the slope in this case?

Slope = 32 Slope indicates the variable cost per unit.

Step-by-step explanation:

As we know that

Total cost is the summation pf fixed cost and variable cost.

Lets take fixed cost =F

Variable cost V=x v

v is the variable cost per unit.

Total cost = F+ V

TC= F + x v

The slope of total cost line is variable cost per unit.

Given that

C= 32x + 560

So from above we can say that

F= 560

V= 32 x

Slope = 32 Slope indicates the variable cost per unit.

f

step-by-step explanation:

f

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
