Q: John buys 500 newspapers. Each newspaper sells for $2. He sells 80% of them. He buys them all for 75% less than the price at which he sells them. How much profit does he make?
A: He sells 500 * .8 = 400 newspapers. He sells them for 400 * 2 = $800. He gets a discount of 2 * .75 = $1.5 on the newspapers. So he buys them for 2 - 1.5 = $.5. So he spent 500 * .5 = $250 buying them. That means he made a profit of 800 - 250 = $550. The answer is 550.
Question: Christopher uses 1 packet of a sugar substitute in his coffee. He has 2 coffees a day. The packets come 30 to a box and cost $4.00 a box. How much will it cost him to have enough sugar substitutes to last him 90 days?
Answer: He uses 1 packet per cup of coffee and he has 2 cups a day so that's 1 * 2 = 2 packets. He wants enough to last him 90 days and he uses 2 packets a day so that's 90 * 2 = 180 packets. The packets come 30 to a box and he needs 180 packets so that's 180 / 30 = 6 boxes of sugar substitute. Each box costs $4.00 and he needs 6 boxes so that's 4 * 6 = $24.00. The answer is 24.
[Question]By the time Anne is two times as old as Emile, Emile will be six times as old as Maude. If Maude will be 8 years old, how old will Anne be?
[Answer]If Maude's age is 8 by the time Anne's age is four times Emile's age, Emile will be six times as old as Maude, which totals 6 * 8 = 48 years. If Emile's age is 48 years old by the time Anne's age is twice her number, Anne will be 2 * 48 = 96 years. The answer is 96.
Q: John drinks 2 energy drinks. 1 of them is a 12-ounce drink with 250 grams of caffeine. The second drink is 3 times more caffeinated per ounce but only 2 ounces. He then takes a caffeine pill that has as much caffeine as his 2 drinks combined. How much caffeine did he consume?
A: The second drink was 2 / 12 = 1 / 6 the size of the first drink. So it had 1 / 6 * 3 = 1 / 2 the caffeine. That means it had 1 / 2 * 250 = 125 grams of caffeine. So the total amount of caffeine he drank was 125 + 250 = 375 grams. So he consumed 375 * 2 = 750 grams of caffeine for the day. The answer is 750.
Question: Wade has a hot dog food truck. He makes $2.00 in tips per customer. On Friday he served 28 customers. He served three times that amount of customers on Saturday. On Sunday, he served 36 customers. How many dollars did he make in tips between the 3 days?
Answer:
On Saturday, he served 3 times the amount of customers that he served on Friday, which was 28 customers so he served 3 * 28 = 84 customers. He served 28 customers on Friday, 84 on Saturday and 36 customers on Sunday for a total of 28 + 84 + 36 = 148 customers. Each customer tipped him $2.00 and he had 148 customers so he made 2 * 148 = $296.00. The answer is 296.
