A town's population is 39,000. About 125 people move out of the town each month. Each month, 175 people on average move into town. A nearby town has a population of 40,200. It has no one moving in and an average of 150 people moving away every month. In about how many months will the populations of the towns be equal? Write an equation to model the situation. Then solve the equation and answer the question. Which equation models the situation? OA. 175m-125m + 40,200=39,000-150m OB. 175m +125m + 40,200=39,000+ 150m O C. 175m-125m+39,000=40,200-150m OD. 175m + 125m+39,000=40,200 + 150m​
