Q: Thomas buys a weight vest. It weighed 60 pounds and worked well for him in the beginning but after a bit of training he decides he wants to increase the weight by 60%. The weights come in 2-pound steel ingots. Each ingot cost $5 and if you buy more than 10 you get a 20% discount. How much does it cost to get the weight he needs?
A: He needs to buy 60 * .6 = 36 pounds. So he needs to buy 36 / 2 = 18 weight plates. That would cost 18 * 5 = $90. Since he bought more than 10 he gets a discount so he gets 90 * .2 = $18 off. That means he paid 90 - 18 = $72. The answer is 72.

Q: Barney the dinosaur weighs 1500 pounds more than five regular dinosaurs combined. If each regular dinosaur weighs 800 pounds, find the combined weight of Barney and the five regular dinosaurs' weights?
A: If each regular dinosaur weighs 800 pounds, five regular dinosaurs weigh 5 * 800 = 4000 pounds. Since Barney the dinosaur weighs 1500 pounds more than five regular dinosaurs combined, he weighs 4000 + 1500 = 5500 pounds. The combined weight of Barney and the five regular dinosaurs' weights is 5500 + 4000 = 9500 pounds. The answer is 9500.

Q: Beckett is 12 and is three years younger than Olaf, while Shannen is two years younger than Olaf. If Jack is five more than twice as old as Shannen, what is the sum of the ages of all 4 people?
A:
Olaf is 12 years + 3 years = 15 years old. Shannen is 15 years old - 2 years = 13 years old. Jack is 5 years + (2 * 13 years) = 31 years old. The sum of all of their ages is 12 + 15 + 13 + 31 = 71 years old. The answer is 71.
