Question

Casey buys and sells used books at his bookstore. He prices all of his used books with a 50% gross profit margin. To do so, he uses the equation: p = 1.5c, where p is price and c is cost. Is this correct? explain.

Answer 1

Yes

Explanation:

Hi, the expression is correct.

Since she wants to price (p) her used books with a 50% gross profit, to do this she has to multiply the cost of the books (c ) by a percent increase (1 + %/100).

So, for a 50% gross

p = (1 + 50/100) c = (1+ 0.5 )c

p= 1.5c
