A 750 ml bottle of spirits costs $30.00 and has 16 servings per bottle.  Most restaurants will charge $8.00 for one serving.  How much money does a restaurant make on a bottle of spirits?
How much do they charge for one serving? ** There are 16 servings in 1 bottle and they charge $8.00 per serving so that's 16*8 = $<<16*8=128.00>>128.00
How much money does a restaurant make on a bottle of spirits? ** 1 bottle yields $128.00 and they spent $30.00 for the bottle so they make 128-30 = $<<128-30=98.00>>98.00 on each bottle
