Answer:
$55
Explanation:
Variable cost of production is the portion of production cost that varies with production amount. In addition to fixed cost it gives total cost of production.
Since there is a +-10% boundary for variable cost. The worst case in terms of high variable cost is 100%+10%= 110%
So worst price = 1.10* 50= $55
On the other hand best case scenario is 100-10= 90%
Best price= 0.9* 50= $45
