Answer:
The total cost at 9000 anchor is $473400
Explanation:
To come up with the cost equation used by the manager, we need to find the variable cost per unit.
The total cost at production level of 5300 is = 5300 * 54 = $286200
Out of the total costs, $18000 are fixed.
Thus, variable costs at production of 5300 is = 286200 - 18000 = $268200
The variable cost per unit is = 268200 / 5300 = $50.60
Let x be the number of anchors produced.
The cost equation is = 18000 + 50.60x
At 9000 anchors, the total cost will be,
Total cost = 18000 + 50.60 * (9000) = $473400
