###Human: Bill picked 50 apples from the orchard with his wife and two children.  He sends each of his kids to school with 3 apples for their two favorite teachers.  His wife Jill bakes two apple pies, using 10 apples per pie. How many apples does Bill have left?, ### Assistant: Bill gives each of his children 3 apples, so since he has two children this is 3*2=6 apples.
Jill bakes 2 apple pies, using 10 apples each so this means she uses 10*2=20 apples.
In total, this means 20+6=26 apples were used.
Since Bill began with 50 apples, this means there are 50-26=24 apples remaining. 
 So the answer is :  24
