A weaver bought a bundle of grass for $ 50.00 from which he made 8 mats. If each mat was sold for $ 15.00, find the percentage profit.
240%
140%
120%
40%
설명
cost price = $50
Selling price = 15 * 8 = $120
percentage profit = \(\frac{sp-cp}{cp}\) * 100 → \(\frac{120-50}{50}\) * 100
percentage profit = 70 * 2 → 140%
