If a ring costs a jeweler $180, at what price should it be sold to yield a profit of 40% on the selling price?

Question

i got $252? but the answer sheet says its wrong

Answer 1

Let x = selling price

what does a profit of 40% mean? Profit = selling price minus cost

x = 180 + .4x

solve for x

.6x = 180

x = 300
