Answer this question:Joyce, Michael, Nikki, and Ryn have a favorite movie. Joyce's favorite movie is 2 hours longer than Michael's movie. Nikki's movie is three times as long as Michael's movie, and Ryn's favorite movie is 4/5 times as long as Nikki's favorite movie. If Nikki's favorite movie is 30 hours long, calculate the total number of hours of their favorite movies together.
Since Nikki's favorite movie is 30 hours long, Ryn's favorite movie is 4 / 5 * 30 = 24 hours long. The total number of hours for Nikki's and Ryn's favorite movies is 24 + 30 = 54 hours long. Nikki's movie is also three times as long as Michael's favorite movie, meaning Michael's favorite movie is 30 / 3 = 10 hours long. Together, Nikki, Ryn, and Michael's favorite movies are 54 + 10 = 64 hours long. If Joyce's favorite movie is 2 hours longer than Michael's favorite movie, then her favorite movie is 10 + 2 = 12 hours long. The length of Nikki, Ryn, Michael, and Joyce's favorite movies is 64 + 12 = 76 hours.
The answer is 76.

Answer this question:In a stationery store, there are three kinds of pencils. A pencil with an eraser, which costs $0.8 each, a regular pencil for $0.5 each, and a short pencil for $0.4 each. This store was able to sell 200 pencils with an eraser, 40 regular pencils, and 35 short pencils. How much money did the store make from these sales?
For pencils with erasers, the store received a total of 200 * 0.8 = $160. For regular pencils, the store received 40 * 0.5 = $20. And for short pencils only 35 * 0.4 = $14. In total, the store made 160 + 20 + 14 = $194 from selling these pencils.
The answer is 194.

Answer this question:In the Oprah Winfrey High School marching band, each trumpet and clarinet player carries 5 pounds of weight, each trombone player carries 10 pounds of weight, each tuba player carries 20 pounds of weight, and each drum player carries 15 pounds of weight. If there are 6 trumpets, 9 clarinets, 8 trombones, 3 tubas, and 2 drummers, how much weight does the total marching band carry?
First find the total number of clarinet and trumpet players: 6 players + 9 players = 15 players. Then find the total weight of the trumpets and clarinets: 15 players * 5 pounds / player = 75 pounds. Then find the total weight of the trombones: 8 players * 10 pounds / player = 80 pounds. Then find the total weight of the tubas: 3 players * 20 pounds / player = 60 pounds. Then find the total weight of the drummers: 2 drummers * 15 pounds / player = 30 pounds. Then add the weight of each type of instrument to find the total weight: 75 pounds + 80 pounds + 60 pounds + 30 pounds = 245 pounds.
The answer is 245.
