Certificate Count

Janelle caught up with Judi at a McDonald's after she'd quit the airport restaurant. She was going through the drive thru, and in a spirit that I highly endorse, decided to screw with Judi. Janelle asked, "How many one dollar certificates can I buy for $5?" "Ummm, hold on, and I'll check with my manager." The manager informed Judi (who relayed it on to Janelle) that you could (amazingly) get five of 'em. But as Janelle grabbed her bag of food she asked, "Can you tell me how many of those certificates $10 would buy?"

Judi dutifully trotted off to talk to the manager again . . .
