A football club has a balance of $100 million. The club then sells 2 of its players at $10 million each, and buys 4 more at $15 million each. How much money is left in the club register in millions of dollars?
Let's think: The 2 players are sold for a total of 2 * 10 = $20 million. So the club has 100 + 20 = $120 million. The cost of buying 4 more players at $15 million each is 4 * 15 = $60 million. So the club now has 120 60 = $60 million.. The answer is: 60.

Cheryl needs 4 cups of basil to make 1 cup of pesto. She can harvest 16 cups of basil from her farm every week for 8 weeks. How many cups of pesto will she be able to make?
Let's think: She harvests 16 cups of basil every week for 8 weeks for a total of 16 * 8 = 128 cups of basil. She needs 4 cups of basil to make 1 cup of pesto and she has 128 cups of basil so she can make 128 / 4 = 32 cups of pesto.. The answer is: 32.

Olaf has an aquarium. He has fish in 3 different colors: orange, green, and blue. Blue fish make up half of all the fish in the aquarium. There are 15 fewer orange fish than blue fish. How many green fish are there when the total number of fish in the aquarium is 80?
Let's think: If there are 80 fish in total, then there are 80 fish / 2 = 40 blue fish. The orange fish count is 15 less than blue, so it's 40 fish - 15 fish = 25 fish. Olaf has then 80 fish - 25 fish - 40 fish = 15 green fish.. The answer is: 15.

Jack needs to put his shoes on, then help both his toddlers tie their shoes. If it takes Jack 4 minutes to put his shoes on, and three minutes longer to help each toddler with their shoes, how long does it take them to get ready?
Let's think:
First figure out how long it takes to help one toddler: 4 minutes + 3 minutes = 7 minutes. Then multiply the time per toddler by the number of toddlers: 7 minutes / toddler * 2 toddlers = 14 minutes. Now add the time spent helping the toddlers to the time Jack spends on his own shoes: 14 minutes + 4 minutes = 18 minutes.. The answer is: 18.
