Hi jjjinapinch,

We're told that Each gift certificate sold yesterday cost either $10 or$50 and that the bookstore sold MORE than 5 gift certificates that cost $50 each. We're asked for the total number of gift certificates sold yesterday by the bookstore. This question can be solved by TESTing VALUES. 1) Yesterday the bookstore sold fewer than 10 gift certificates that cost$10 each.

Fact 1 tells us that there could be from 0-10 $10 certificates and 6 or more$50 certificates, but we don't know the TOTAL certificates sold.
Fact 1 is INSUFFICIENT

2) The total cost of gift certificates sold yesterday by the bookstore was $460. IF... 8$50 certificates and 6 $10 certificates were sold, then the answer to the question is 14. 9$50 certificates and 1 $10 certificates were sold, then the answer to the question is 10. Fact 2 is INSUFFICIENT Combined, we already have two TESTs that 'fit' both Facts and provide different results: 8$50 certificates and 6 $10 certificates were sold, then the answer to the question is 14. 9$50 certificates and 1 \$10 certificates were sold, then the answer to the question is 10.
Combined, INSUFFICIENT

GMAT assassins aren't born, they're made,
Rich
