Every month we will give you a math/statistics brain teaser that lets you test your
knowledge with a fun problem.
This Month's Challenge: Coffee
Donna studied for an exam at a coffee shop. She bought a muffin for $3, a coffee
for $4, and a sandwich for $6.
If she came into the coffee shop with $20, how much did she have when she left?
Click here for answer!
Step 1: Find the amount of money Donna spent.
Add the prices of the muffin, coffee, and sandwich.
Step 2: Find the amount of money Donna had left.
Subtract the amount she spent from the amount she had.
Donna had $7 when she left the coffee shop.
Many of the ideas in these Teasers come from thoughts formed by some of the great
mathematical/statistical geniuses in history. To learn more about them and to take
