part a is correct, need help finding which vikune site A is reccomended and B. thanks

Hyundai Motors is considering three sites-A, B, and C-at which to locate a factory to build its new electric car batteries. The goal is to locate at a minimum-cost site, where cost is measured by the annual fixed plus variable costs of production. Hyundai Motors has gathered the following data: The firm knows it will produce between 0 and 60,000 batteries at the new plant each year, but, thus far, that is the extent of its knowledge about production plans. a) The value of volume, V, of production above which site C is recommended = batteries (round your response up to the next whole number). b) The value of volume, V, of production below which site A is recommended = batteries (round your response up to the next whole number). At the crossover point, the total cost of each of the alternatives being compared is equal and the following relationship can be used: CrossoverPointXvsY=VariableCostCosYVariableCostXFixedCostXFixedCostY
