A store sells erasers for 0.23$per piece and pencil for 0.11$ per piece. How many eraser and pencils did Jessica buy?

(1) She bough 5 erasers. Clearly insufficient.

(2) She spent total of 1.70$--> $$0.23e+0.11p=1.70$$ --> $$23e+11p=170$$ --> by trial and error we can find that the only non-negative integer solution for this equation is e=5 and p=5. Sufficient. Answer: B. _________________ Math Expert Joined: 02 Sep 2009 Posts: 39066 Followers: 7760 Kudos [?]: 106604 [0], given: 11630 Re: A store sells erasers for 0.23$ per piece and pencil for 0.1 [#permalink]
