Q: Richard can clean his room in 22 minutes. Cory takes 3 minutes more than Richard to clean her room while Blake can clean his room 4 minutes more quickly than Cory. If they have to clean their rooms twice a week, how many minutes do all three spend cleaning their rooms each week?
A: Cory takes 22 + 3 = 25 minutes to clean her room. Blake takes 25 - 4 = 21 minutes to clean his room. The three of them can clean their room in 22 + 25 + 21 = 68 minutes in all. In a week, they spend 68 x 2 = 136 minutes cleaning their rooms. The answer is 136.
Question: 1,800 fish swim westward, 3,200 swim eastward, and 500 swim north. What is the number of fish left in the sea, if fishers catch 2/5 of the fish that swam eastward and 3/4 of the fish that swam westward?
Answer: When fishers caught 3 / 4 of the fish that swam westward, their total number reduced by 3 / 4 * 1800 fish = 1350. The total number of fish that remained from the total number that swam eastward is 1800 fish - 1350 fish = 450 fish. If fishers caught 2 / 5 of the fish that swam eastward, their total number reduced by 2 / 5 * 3200 fish = 1280 fish. 3200 fish - 1280 fish = 1920 fish remained in the sea from the number that swam westward. The total number of fish in the sea after fishers caught some is 500 of the number that went north + 450 of the fish that swam westward + 1920 of the fish that swam eastward = 2870 fish. The answer is 2870.
[Question]Uki owns a bakery. She sells cupcakes at $1.50 each, cookies at $2 per packet, and biscuits at $1 per packet. In a day, she can bake an average of twenty cupcakes, ten packets of cookies, and twenty packets of biscuits. How much will be her total earnings for five days?
[Answer]Uki earns 20 x $1.50 = $30 in selling 20 cupcakes. She earns 10 x $2 = $20 for selling 10 packets of cookies,. Additionally, she earns another 20 x $1 = $20 for selling twenty packets of biscuits. Thus, in a day, she earns an average of $30 + $20 + $20 = $70.                                    Therefore, for five days, Uki earns 5 x $70 = $350. ". The answer is 350.
[Question]Hortense loves daisies and sunflowers. She planted 25 daisy seeds and 25 sunflower seeds in her flower bed. If 60% of the daisy seeds germinate, and 80% of the sunflower seeds germinate, and 80% of the resulting plants produce flowers, how many plants will she grow that produce flowers?
[Answer]
At a germination rate of 60%, 25 seeds will yield 60 / 100 * 25 = 15 plants. At a germination rate of 80%, 25 seeds will yield 80 / 100 * 25 = 20 plants. In total, she will have grown 15 + 20 = 35 plants. If 80% of the plants developed flowers, then she will have grown (80 / 100) * 35 = 28 plants that produce flowers. The answer is 28.
