All right, class, here’s a math puzzle for you:
A woman went to an office supply store. The birds were singing and the flowers were in bloom. The woman purchased:
- A super-duper, all-in-one wireless printer for $99.00.
- A handy-dandy, combination accessory kit for $39.00.
- A long-coveted label maker for $19.00.
The exceedingly charming salesman pointed out that, since the woman purchased items one and three together, an extra $10.00 would be deducted from the price of the printer at the register. He pointed to a neon cardboard sign near the printer that verified his words. The woman was happy.
Later, as the woman studied the receipt, the flowers melted like wax in the sun as her glad became sad. Please study the receipt for yourself, and explain how an apparent $20.00 discount (as in double ten) became zero.
Show your work, and explain your answer.
Note: If you are having trouble explaining the puzzle, don’t worry. The store manager did, too.
Math tip of the Day: Always check your receipt work.
