Final answer:
The selling price for the shipment of Peruvian opals that Ben Supple received, considering a 68% markup based on the selling price, is calculated to be $500.
Step-by-step explanation:
The student is asking how to calculate the selling price of a shipment of Peruvian opals with a markup based on the selling price. A 68% markup on the selling price means that 68% of the selling price is the profit on top of the cost of the shipment, which is $160. To find the selling price, let's denote it as S. We'll set up the equation where the cost plus the markup equals the selling price:
160 + (0.68 × S) = S
Solving for S, we get:
160 = S – (0.68 × S)
160 = S × (1 – 0.68)
160 = S × 0.32
S = 160 / 0.32
S = $500
Thus, the selling price Ben Supple should set for the shipment of Peruvian opals is $500.
