Answer this question:There are 11 males & 12 females in the orchestra and twice that number in the band. There are 12 males & 17 females in the choir. If each musician only participates in one group, how many musicians total are there in the orchestra, the band, and the choir?
The number of musicians in the orchestra is 11 + 12 = 23. The number of musicians in the band is 2 × 23 = 46. The number of students in the choir is 12 + 17 = 29. There are 23 + 46 + 29 = 98 musicians in total.
The answer is 98.

Answer this question:Carl wants to buy a new coat that is quite expensive. He saved $25 each week for 6 weeks. On the seventh week, he had to use a third of his saving to pay some bills. On the eighth week, his dad gave him some extra money for him to buy his dream coat. If the coat cost $170, how much money did his dad give him?
Carl saved in 6 weeks $25 / week x 6 weeks = $150. On the seventh week, he ended up having to pay in bills $150 / 3 = $50. His savings were then $150 - $50 = $100. His dad gave him $170 – $100 = $70.
The answer is 70.

Answer this question:In a restaurant, a burger costs $9, and a pizza twice as much. How much would cost one pizza and three burgers?
One pizza costs twice as much as the burger, which means 9 * 2 = $18. Three burgers would cost 9 * 3 = $27. So one pizza and three burgers would cost in total 18 + 27 = $45.
The answer is 45.

Answer this question:Tom fills a 250 pound sandbag 80% full. But the filling material he is using is 40% heavier than sand. How much does the bag weigh?
The bag full of sand would weigh 250 * .8 = 200 pounds. The filling material would make it 200 * .4 = 80 pounds heavier. So it weighs 200 + 80 = 280 pounds.
The answer is 280.
