Jeff decides to install more cabinets in his kitchen. He currently has 3 cabinets over one counter and no other cabinets. He installs twice as many cabinets over 3 different counters each. He then installs 5 more cabinets. How many total cabinets does he have? Give the rationale and then the answer.
Let's think step by step. He installs 3 * 2 = 6 cabinets over each counter. So he installs 6 * 3 = 18 cabinets over counters. That means he installed a total of 18 + 5 = 23 cabinets. So he has 23 + 3 = 26 cabinets.. The answer is: 26.

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? Give the rationale and then the answer.
Let's think step by step. 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.

A trader made a profit of $960 after a week of sales. To raise $610 to pay for her next shipment of wares, she splits the profit in half and solicits donations from her family and friends. If she received a total donation of $310 and adds it to one-half of her profit, how much money did she make above her goal? Give the rationale and then the answer.
Let's think step by step. She splits her $960 profit in half to get $960 / 2 = $480. She receives a total donation of $310, so she now has $310 + $480 = $790. She needed only $610 so she has $790 - $610 = $180 more than she needs.. The answer is: 180.
