[Question]An online newspaper had listed 100 visitors in October. The number of visitors in November increased by 15%. There were 15 more visitors in December than in November. What is the total number of visitors for these three months?
[Answer]There was an increase of 100 x 15 / 100 = 15 visitors in November. So, the number of visitors in November was 100 + 15 = 115. In December, the number of visitors was 115 + 15 = 130. Therefore, a total of 100 + 115 + 130 = 345 visitors listed in these three months. The answer is 345.
Q: Jimmy wants to play in the inflatable swimming pool in his backyard. The swimming pool is empty and the garage is locked, so he cannot use the hose to fill the pool. He finds a 2 gallon bucket and calculates that it takes 20 seconds to fill the bucket from the tap and carry it to the pool where he pours in the water. If the pool holds 84 gallons of water, how many minutes will it take Jimmy to fill the pool?
A: It will take 84 / 2 = 42 trips to fill the pool with water. This will take Jimmy 42 trips * 20 seconds per trip = 840 seconds. This means that Jimmy will spend 840 seconds * 1 minute / 60 seconds = 14 minutes filling the pool. The answer is 14.
Question: In a 100-item exam, Lowella got 35% of the questions correctly. Pamela got 20% more correct answers than Lowella and Mandy got twice Pamela's score. What is Mandy's score?
Answer: Lowella got 100 x 35 / 100 = 35 correct answers. Pamela got 35 x 20 / 100 = 7 more correct answers than Lowella. So, Pamela got 35 + 7 = 42 correct answers. Thus, Mandy got 42 x 2 = 84 correct answers. The answer is 84.
[Question]Alice needs to sell $1000 of shoes to meet her quota. Adidas cost $45, Nike cost $60, and Reeboks cost $35. If she sells 8 Nikes, 6 Adidas's, and 9 Reeboks, how much is she short or above her goal?
[Answer]The total dollar amount of Nike's sold is 8 * $60 = $480. The total dollar amount of Adidas's sold is 6 * $45 = $270. The total dollar amount of Reebok's sold is 9 * $35 = $315. The total dollar amount that Alice sold was $480 + $270 + $315 = $1065. Therefore, she sold above her goal by $1065 - $1000 = $65. The answer is 65.
Q: Samantha bought a crate of 30 eggs for $5. If she decides to sell each egg for 20 cents, how many eggs will she have left by the time she recovers her capital from the sales?
A: There are 100 cents in each $1 so $5 gives 5 * 100 cents = 500 cents. To recover her capital of 500 cents from a selling price of 20 cents per egg she has to sell 500 / 20 = 25 eggs. There were 30 eggs in the crate to start with so she will have 30 - 25 = 5 eggs left. The answer is 5.
