[Question]: Sally Draper gave her dad Don Draper 10oz of rum on his pancakes. Don can consume a maximum of 3 times that amount of rum for a healthy diet. If he already had 12oz of rum earlier that day, how many oz of rum can Don have after eating all of the rum and pancakes?
[Answer]: 3 times the initial amount of 10 oz is 3 * 10 = 30 oz. He has consumed 10 + 12 = 22 oz of rum. He can still consume 30 - 22 = 8 oz of rum.
So the answer is 8.

[Question]: A pastry chef is making brownies but is running out of butter. The recipe he is following calls for 2 ounces of butter for every 1 cup of baking mix; however, it allows 2 ounces of coconut oil to be substituted for the 2 ounces of butter if necessary. The chef would like to use as much butter as possible before switching over and substituting coconut oil. If the chef had 4 ounces of butter remaining, and he plans on using 6 cups of baking mix, how many ounces of coconut oil will he end up using?
[Answer]: Every 2 ounces of butter is enough to cover 1 cup of baking mix, so the chef's remaining 4 ounces of butter will be enough to cover 4 / 2 = 2 cups of baking mix. This leaves 6 - 2 = 4 cups of baking mix that will require the use of coconut oil as a substitute. Since each cup of baking mix requires 2 ounces of coconut oil, these 4 cups will require a total of 4 * 2 = 8 ounces of coconut oil.
So the answer is 8.

[Question]: Jason and Jeremy want to paint their wall white and agreed to split the cost of the paint. A gallon of paint costs $45 and can cover up to 400 square feet. How much will each of them contribute to the cost of the paint if their walls have a total area of 1600 square feet and will need a second coat?
[Answer]:
They need 1600 square feet / 400 square feet / gallon = 4 gallons of paint for their walls. Since they will do a second coating, then they would need 4 gallons x 2 = 8 gallons in all. Eight gallons of paint will cost $45 / gallon x 8 gallons = $360. Thus, Jason and Jeremy will each contribute $360 / 2 = $180.
So the answer is 180.
