[Question]Patrick has 4 hours less than twice the amount of time that Greg has left to finish his homework. Greg has six hours less than Jacob left to finish his homework. If Jacob has 18 hours left to finish his homework, calculate the total number of hours they all have left to finish their homework?
[Answer]If Jacob has 18 hours left to finish his homework, Greg has 18 - 6 = 12 hours left to finish his homework. The total number of hours Jacob and Greg have left to finish their homework is 12 + 18 = 30 hours. Patrick has 4 hours less than twice Greg has left to finish his homework, meaning Patrick has 4 hours less than 12 * 2 = 24 hours left to finish his homework. Patrick has 24 - 4 = 20 hours left to finish his homework. Altogether, the three have 30 + 20 = 50 hours left to finish their homework. The answer is 50.
Q: Rebecca makes her own earrings out of buttons, magnets, and gemstones. For every earring, she uses two magnets, half as many buttons as magnets, and three times as many gemstones as buttons. If Rebecca wants to make 4 sets of earrings, how many gemstones will she need?
A: Four sets of earrings is 2 * 4 = 8 earrings. Since for one earring, she uses two magnets, for eight earrings she uses 2 * 8 = 16 magnets. Since she uses half as many buttons as magnets, then for 8 earrings she would use 16 / 2 = 8 buttons. Since she uses three times as many gemstones as buttons, then in 8 earrings, she will use 8 * 3 = 24 gemstones. The answer is 24.
Question: To make yogurt, the company needs milk and fruit. Milk is bought at $1.5 per liter and fruit at $2 per kilogram. To make one batch of yogurt, the company needs 10 liters of milk, and 3 kilograms of fruit. How much does it cost the firm to produce three batches of yogurt?
Answer: For the fruits, the company needs to pay 3 * 2 = $6 per batch. 10 liters of milk is a cost of 10 * 1.5 = $15 for the company. So in total one batch is a cost of 15 + 6 = $21. So three batches of yogurt is a cost of 3 * 21 = $63. The answer is 63.
