Five years ago, a house was purchased for 123,500. This year it was appraised at 185,000. Question: Find the average rate of change. Then use it to estimate the value of the house in 7 years.

The average rate of change is the "change in value over the change in time."

The house has increased in value at an average rate of $12,300/year.

Assuming the same rate of change,  in seven years the value will increase by 7x12300:

The house should be worth about $271,100 in seven year from now.
