Q: A baker bakes 5 loaves of bread an hour in one oven. He has 4 ovens. From Monday to Friday, he bakes for 5 hours, but on Saturday and Sunday, he only bakes for 2 hours. How many loaves of bread does the baker bake in 3 weeks?
A: In an hour, the baker bakes 5 x 4 = 20 loaves of bread. From Monday to Friday, he bakes 5 x 20 = 100 loaves of bread per day. From Monday to Friday, he bakes a total of 100 x 5 = 500 loaves of bread. On Saturday and Sunday, he bakes 2 x 20 = 40 loaves of bread per day. On Saturday and Sunday, he bakes a total of 40 x 2 = 80 loaves of bread. In a week, he bakes 500 + 80 = 580 loaves of bread. In 3 weeks, he bakes 580 x 3 = 1740 loaves of bread. The answer is 1740.

Q: Darryl is an inventor who just designed a new machine. He had to pay $3600 for the parts to construct the machine, and $4500 for the patent he applied for once he built it. If the machine sells for $180, how many machines does Darryl need to sell to break even after the costs?
A: Darryl paid 3600 + 4500 = $8100 in costs for the parts and patent. Thus, Darryl needs to sell 8100 / 180 = 45 machines to break even. The answer is 45.

Q: Marcy had 22 sodas in her fridge for a party. Her friend Tina came over and gave her 12 plus two times the number of sodas Marcy had before. How many sodas will Marcy have for the party?
