A​ town's population is 47,500. About 75 people move out of the town each month. Each​ month, 125 people on average move into town. A nearby town has a population of 50,250. It has no one moving in and an average of 200 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.

• 125m-75m+50,250=47,500-200m
• 75m-125m+ 50,250 = 47,500-200m
• 75m-125m+47,500 = 50,250-200m
• 125m-75m+47,500 = 50,250-200m

The total weight of a computer hard drive, a monitor, and a keyboard is 362 ounces.  The hard drive weighs 318 ounces and the monitor weighs 33 ounces.  Which equation represents the situation where k is the weight of the keyboard?

• 362 = 318 + 33 - k
• 362 = 318 + 33 + k
• 362 = 318 + k
• 362 = 318 - k
