Q: Tina makes $18.00 an hour. If she works more than 8 hours per shift, she is eligible for overtime, which is paid by your hourly wage + 1/2 your hourly wage. If she works 10 hours every day for 5 days, how much money does she make?
A: She works 8 hours a day for $18 per hour so she makes 8 * 18 = $144.00 per 8 - hour shift. She works 10 hours a day and anything over 8 hours is eligible for overtime, so she gets 10 - 8 = 2 hours of overtime. Overtime is calculated as time and a half so and she makes $18 / hour so her overtime pay is 18 * .5 = $9.00. Her overtime pay is 18 + 9 = $27.00. Her base pay is $144.00 per 8 - hour shift and she works 5 days and makes 5 * $144 = $720.00. Her overtime pay is $27.00 per hour and she works 2 hours of overtime per day and makes 27 * 2 = $54.00 in overtime pay. 2 hours of overtime pay for 5 days means she makes 54 * 5 = $270.00. In 5 days her base pay is $720.00 and she makes $270.00 in overtime pay so she makes $720 + $270 = $990.00. The answer is 990.
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?
Answer: 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.
[Question]The perimeter of a square-shaped piece of paper is 20 cm shorter than the height of a computer screen. How many cm is the height of the screen if the side of the square paper is 20 cm?
[Answer]The perimeter of a square is found by 4 * side, which means the square paper has a perimeter of 4 * 20 = 80. Since the perimeter of the square is 20 cm shorter than the height of the computer screen, the height of the computer screen is 20 + 80 = 100cm. The answer is 100.
[Question]Richard can clean his room in 22 minutes. Cory takes 3 minutes more than Richard to clean her room while Blake can clean his room 4 minutes more quickly than Cory. If they have to clean their rooms twice a week, how many minutes do all three spend cleaning their rooms each week?
[Answer]
Cory takes 22 + 3 = 25 minutes to clean her room. Blake takes 25 - 4 = 21 minutes to clean his room. The three of them can clean their room in 22 + 25 + 21 = 68 minutes in all. In a week, they spend 68 x 2 = 136 minutes cleaning their rooms. The answer is 136.
