Question: Stacy, Steve and Sylar have 1100 berries total. Stacy has 4 times as many berries as Steve, and Steve has double the number of berries that Skylar has. How many berries does Stacy have?
Answer: Let x be the number of berries Skylar has. Steve has 2x berries. Stacy has 4(2x) = 8x berries. 1100 = x + 2x + 8x. 1100 = 11x. x = 100 berries. Stacy has 8(100) = 800 berries. The answer is 800.

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?
Answer: 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.

Question: Alice has 20 quarters. She wants to exchange them for nickels and so she goes to the bank. After getting back from the bank, she discovers that 20% of the nickels are iron nickels worth $3 each. What is the total value of her money now?
Answer: A quarter is worth five nickels because .25 / .05 = 5. She gets 100 nickels from the bank because 20 x 5 = 100. 20 of the nickels are iron nickels because 100 x .20 = 20. 80 of the nickels are regular because 100 - 20 = 80. The iron nickels are worth $60 because 20 x 3 = 60. The regular nickels are worth $4 because 80 x .05 = 4. Her money is now worth $64 because 60 + 4 = 64. The answer is 64.

Solomon is 3 * Juwan so Juwan is 1 / 3 of Solomon = 66 / 3 = 22. Levi collected half of 22 = 11. Combined the boys collected 66 + 22 + 11 = 99 cans in all. The answer is 99.
