David bought a game on sale for $6 less than half its original price. she paid $88 for the jacket. what was the original price

We can't tell with the information given.  We don't know the connection
between the price David paid for the game, and the price his sister paid
for the jacket. 

This question is a lot like a radio station out in the country at night that's
not tuned in very well, or a billboard with part of the top layer peeled off.

Idon’t know how to do that
