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.

Question: A factory decides to stop making cars and start making motorcycles instead. When it made cars, per month, it cost $100 for materials, they could make 4 cars, and they sold each car for $50. Now that they make motorcycles it costs $250 for materials, but they sell 8 of them for $50 each. How much more profit do they make per month selling motorcycles instead of cars?
Answer: They sold $200 worth of cars each month because 4 x 50 = 200. They made $100 a month off cars because 200 - 100 = 100. They sold $400 worth of motorcycles each month because 8 x 50 = 400. They make $150 a month off motorcycles because 400 - 250 = 150. They make $50 more a month off motorcycles than cars because 150 - 100 = 50. The answer is 50.

The slippers are $50.00 and currently 10% off so that’s 50 * .10 = $5.00 discount. The slippers are $50.00 with a $5.00 discount which makes them 50 - 5 = $45.00. The embroidery will be $5.50 per shoe, and 2 shoes make a pair so it will cost 5.50 * 2 = $11.00. The shoes are on sale for $45.00, the embroidery will be $11.00 and the shipping is $10.00 for a total of 45 + 11 + 10 = $66.00. The answer is 66.
