$\underline{\text { Folklore }}$

Vanya went to the shooting range with his dad. The deal was this: Vanya would be given 10 bullets, and for each hit on the target, he would receive three more bullets. Vanya made 14 shots, and he hit the target exactly half of the time. How many bullets did Vanya have left?
Vanya hit the target 7 times, so he received 21 additional cartridges. Since he initially had 10 cartridges, he ended up with a total of 31 cartridges. Vanya made 14 shots, so 17 cartridges remained.

## Answer

17 cartridges.
