Answer:
TC = $1,700 + $20x
P = $20x - $1,700
x = 85
Explanation:
Develop a mathematical model for the total cost of producing x pairs of shoes.
The total cost of producing x pairs is given by the fixed cost of $1700 added to a variable cost of $20 per pair. For x pairs:
[tex]TC =\$1,700 + \$20x[/tex]
Let P indicate the total profit. Develop a mathematical model for the total profit realized from an order for x pairs of shoes.
Total profit is given by Revenue from sales minus total costs (found on the previous item). Revenue is $40 per pair. The profit function is:
[tex]P = \$40x-(\$1,700 + \$20x)\\P = \$20x-\$1,700[/tex]
How large must the shoe order be before O'Neill will break even?
The break-even point occurs when profit is zero:
[tex]0 = \$20x-\$1,700\\x=85[/tex]
The shoe order must be at least 85 pairs.
