Q: When Diane turns 30, she will be half the age of Alex and twice as old as Allison. Diane is 16 years old now. What is the sum of the ages of Alex and Allison now?
A: When Dianne turns 30, Alex will be 30 x 2 = 60 years old. Allison will be 30 / 2 = 15 years old then. Dianne will turn 30 in 30 - 16 = 14 years. Currently, the age of Alex is 60 - 14 = 46. Currently, Allison is 15 - 14 = 1 year old. So, the sum of Alex and Allison's ages now is 46 + 1 = 47 years old. The answer is 47.
Question: Lindsey owns 4 more cars than Cathy. Susan owns 2 fewer cars than Carol. Carol owns twice as many cars as Cathy. If Cathy owns 5 cars, how many total cars do they all own put together?

Q: Leila spent 3/4 of her savings on make-up and the rest on a sweater. If the sweater cost her $20, what were her original savings?
A: If Leila spent 3 / 4 of her savings on make - up, this means she spent 1 - 3 / 4 = 1 / 4 of her savings on a sweater. Let S be her original savings. If the sweater cost $20, this means 1 / 4 * S = $20. Thus S = $20 * 4 = $80. The answer is 80.
Question: Cary is trying to strip the ivy off a tree in her yard. She strips 6 feet of ivy every day, but the ivy grows another 2 feet every night. If the tree is covered by 40 feet of ivy, how many days will it take Cary to strip all the ivy off?
Answer: First find the net amount of ivy Cary removes each day by subtracting the ivy's growth from the amount she removes: 6 feet / day - 2 feet / day = 4 feet / day. Then divide the total feet of ivy by the net amount Cary removes each day to find how many days it takes her to remove all the ivy: 40 feet / 4 feet / day = 10 days. The answer is 10.
Q: Allen ordered five boxes of pizza, which cost $7 each box. He then gave a tip which amounts to 1/7 of the total cost of his order. If he gave the delivery man $100, how much change did he receive?
A:
The total cost of five boxes of pizza is $7 x 5 = $35. He gave $35 x 1 / 7 = $5 tip to the delivery man. He spent a total of $35 + $5 = $40 for the pizza and the tip. The change that he received is $100 - $40 = $60. The answer is 60.
