Answer:
The answer to your question is: Ann took 13 cupcakes to school.
Step-by-step explanation:
Data
Initial amount of cupcakes = 26
cupcakes to school = c
cupcakes to soccer = 12
cupcakes left = 3
Process
Initial cupcakes = 28
Initial amount = cupcakes to school + cupcakes to soccer + cupcakes left
28 = c + 12 + 3
c = 28 - 12 - 3
c = 13
