What is X?

Question

Great Gifts pays its supplier 65$ for each box of 12 bells. The owner wants to determine the minimum amount X he can charge his customers per bell in order to make at least 50% profit per box. What is X?

Answer 1

cost = $65

profit ≥ $32.50      (50% of $65)

price/box ≥ $97.50

price/bell ≥ $8.125  ($97.50 / 12)
