First, we need to restate the problem as thus: For every 70 cents, one can buy 72 pencils (equal to 6 dozen pencils). Thus, for every x cents, one can buy 3 pencils. In numerical form, this equation turns into $0.70/72 pencils = $x/3 pencils, or 0.70/72 = x/3. Simplified, one gets (3)(0.70) = 72x, or 2.1 = 72x. Hence, x=2.1/72=0.029, or $0.03, or 3 cents. So 3 pencils actually cost 3 cents. If one were to sell 3 pencils for 20 cents, one would have a profit of 17 cents for 3 pencils.
