Question: Carolyn is trimming a dress with lace around the cuffs, waist, hem, and neckline. Each cuff is 50 cm long, the hem is 300 cm long, the waist is a third of the length of the hem, and the neck will have 5 ruffles that each use 20 cm of lace. If lace costs $6/m, how much does Carolyn spend on lace?
Answer: First find the length of the waist: 300 cm / 3 = 100 cm. Then find the total amount of lace she uses on the cuffs: 2 cuffs * 50 cm / cuff = 100 cm. Then find the total amount of lace she uses on the ruffles: 5 ruffles * 20 cm / ruffle = 100 cm. Then add each amount of lace she uses to find the total: 100 cm + 100 cm + 100 cm + 300 cm = 600 cm. Then convert that length to meters to by dividing by 100: 600 cm / 100 cm / m = 6 m. Finally, multiply the total meters of lace needed by the cost per meter to find the total cost: 6 m * $6 / m = $36. The answer is 36.

Question: In 5 years, Frank will be three times as old as Ty is now. Ty is currently 4 years more than two times as old as Carla is now. Carla is currently 2 years older than Karen is now. If Karen is currently 2 years old, how old will Frank be in 5 years?
Answer: Carla is currently 2 + 2 = 4 years old. Ty is currently (2 * 4) + 4 = 12 years old. In 5 years, Frank will be 12 * 3 = 36 years old. The answer is 36.

Question: John cuts his grass to 2 inches. It grows .5 inches per month. When it gets to 4 inches he cuts it back down to 2 inches. It cost $100 to get his grass cut. How much does he pay per year?
Answer: He cuts his grass 4 - 2 = 2 inches. So he gets it cut every 2 / .5 = 4 months. That means he gets it cut 12 / 4 = 3 times a year. So he pays 100 * 3 = $300 per year. The answer is 300.
