Mr. and Mrs. Miller both get in their cars and begin to drive at the same time. Mr. Miller is 280 mi from their house and drives directly home at a constant rate of 40 mph. Mrs. Miller is at their house and drives away from the house at a constant rate of 30 mph. Let d represent distance from home, and let t represent time in hours. Which system models this situation? A. d = 280 + 40t d = 30t B. d = 280 − 30t d = 40t C. d = 280 − 40t d = 30t D. d = 280 − 40t d = 280 + 30t

Laura fills a bucket with water at a rate of 6 L/min. At the same time, Sarah empties a bucket holding 30 L of water at a rate of 9 L/min. Let l represent the number of liters of water and let t represent time in minutes. The system models this situation. How many minutes will it take for the buckets to hold equal amounts of water, and how much water will that be? l = 6t l = 30 – 9t It will take minutes for both buckets to hold equal amounts of water. They will each hold liters.

Carissa and Louann both have savings accounts. Carissa has $250 in her account and deposits $80 per month. Louann has $1230 in her account and withdraws $60 per month. After how many months will they have equal amounts of money in their accounts? What amount of money will each have when it is the same amount? It will take months. Then, they will both have $ in their accounts.
