Answer: John will have 7 cupcakes left. John made 11 vanilla and 9 chocolate.
Step-by-step explanation:
1. Do 11+9. That will give you the total of cupcakes John had before he started selling them.
2. 11+9=20. John had 20 cupcakes before he started selling.
3. He's selling cupcakes. He sold 13 cupcakes.
4. Since 11+9=20, you would subtract 20-13.
5. 20-13=7/
John has 7 cupcakes left. :)
