Question 2155: a man sold two-thirds of his pencils for 20 cents each. If he has 7 pencils left, how much money did he collect for the pencils he sold? Answer by longjonsilver(2297) (Show Source):
You can put this solution on YOUR website! Let x=Total number of pencils.
So, he sold 2/3 and kept 1/3. This one third is really 7 pencils...so
(1/3)x = 7, so x=21.
So he sold 14 pencils, each at 20 cents = 280 cents or $2.80.
