Answer this question: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?
There are 16 servings in 1 bottle and they charge $8.00 per serving so that's 16 * 8 = $128.00. 1 bottle yields $128.00 and they spent $30.00 for the bottle so they make 128 - 30 = $98.00 on each bottle.
The answer is 98.

Answer this question:Josh buys 3 packs of string cheese. Each piece of string cheese cost 10 cents. Each pack has 20 string cheeses in them. How many dollars did he pay?
Each pack cost 20 * 10 = 200 cents. So each pack cost 200 / 100 = $2. That means he pays 2 * 3 = $6.
The answer is 6.

Answer this question:Billy has $25 less than twice the money Sam has. If Sam has $75, how much money do they have together?
Billy has $25 less than twice Sam's money, or 2 * $75 - $25 = $150 - $25 = $125. Together they have $75 + $125 = $200.

Answer this question:There's a Bobbit worm hiding in the bottom of James' aquarium. Every day it eats 2 fish. After two weeks, James adds 8 more fish to the aquarium. A week later, he discovers the Bobbit worm. If the aquarium had 60 fish to start with, how many does it have when James discovers the Bobbit worm?
First find the total number of weeks the Bobbit worm preys on the fish: 2 weeks + 1 week = 3 weeks. Then multiply that number by the number of days per week: 3 weeks * 7 days / week = 21 days. Then multiply that number by the number of fish the worm eats per day to find how many fish it eats total: 21 days * 2 fish / day = 42 fish. Then add the number of fish James adds to the starting number of fish to find the ending number of fish: 60 fish + 8 fish = 68 fish. Then subtract the number of eaten fish to find the number of surviving fish: 68 fish - 42 fish = 26 fish.
The answer is 26.
