Answer this question:An airline company owns 5 airplanes. Every airplane they own has 20 rows with 7 seats in each row. Each airplane makes 2 flights a day. How many passengers can the airline company accommodate each day?
Each airplane has 20 x 7 = 140 seats. So, the 5 airplanes can accommodate a total of 140 x 5 = 700 passengers. Therefore, the airline company can accommodate 700 x 2 = 1400 passengers each day.
The answer is 1400.

Answer this question:Nancy's ex owes her child support. He's supposed to pay 30% of his income each year. For 3 years, he made $30,000/year, then he got a 20% raise for the next four years. If he's only ever paid $1,200, how much does he owe her?
First find how much money the ex made during the first 3 years by multiplying his annual earnings by the number of years: 3 years * $30,000 / year = $90,000 / . Then find how much his raise was by multiplying his salary by the percentage raise: $30,000 / year * 20% = $6,000 / year. Then add the raise to his original salary to find his new salary: $6,000 / year + $30,000 / year = $36,000 / year. Then find how much he made working at the new salary by multiplying it by the 4 years he worked: 4 years * $36,000 / year = $144,000. Add his earnings from the three years and the four years to find his total earnings: $144,000 + $90,000 = $234,000. Now multiply his total earnings by 30% to find how much he was supposed to pay: $234,000 * 30% = $70,200. Now subtract the amount he paid from this number to find how much he owes: $70,200 - $1,200 = $69,000.
The answer is 69000.

Answer this question:TreShaun's full marker has enough ink in it to paint three 4 inch by 4 inch squares. If he colors in two 6 inch by 2 inch rectangles, what percentage of ink is left?
Each 4 by 4 square equals 16 square inches because 4 x 4 = 16. Three squares equals 48 square inches because 3 x 16 = 48. Each rectangle uses 12 square inches because 2 x 6 = 12. Both rectangles will use 24 square inches because 2 x 12 = 24. He has 1 / 2 of the ink left because 24 / 48 = 1 / 2. He has 50% of the ink left because 1 / 2 x 100 = 50.
The answer is 50.

Answer this question:It's exam season and Tristan has several exams to prepare for. On Monday, he studies for 4 hours then studies for twice this long on Tuesday. On Wednesday, Thursday, and Friday he studies for 3 hours each day. He wants to study for a total of 25 hours over the week and divides the remaining amount of study time evenly between Saturday and Sunday. How many hours does Tristan spend studying on Saturday?
On Tuesday, Tristan studies twice as long as he did on Monday and this amounts to 4 hours * 2 = 8 hours. So in the first 5 days of the week, he studies for a total of 4 hours Monday + 8 hours Tuesday + 3 hours Wednesday + 3 hours Thursday + 3 hours Friday = 21 hours. He therefore has 25 planned hours 21 used hours = 4 hours left to study. As he splits his time evenly over 2 days, he spends 4 hours / 2 = 2 hours studying on Saturday.
The answer is 2.
