The o'neill shoe manufacturing company will produce a special-style shoe if the order size is large enough to provide a reasonable profit. for each special-style order, the company incurs a fixed cost of $1000 for the production setup. the variable cost is $40 per pair, and each pair sells for $50. let x indicate the number of pairs of shoes produced. develop a mathematical model for the total cost of producing x pairs of shoes. express your answer in terms of x.

  c(x) = 1000 +40x

Step-by-step explanation:

The total cost c will be the sum of the fixed cost and the product of the variable cost per pair and the number of pairs.

  c(x) = 1000 +40x

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

what i would say the best answer is a. 40.5
