Using the information given, calculate a grade to the nearest whole percent. the "rise" is 525 feet. if the scale on the map showed the "run" on the west side is 800 feet. the grade on the west side would be

the rise on the east side will still be 525 feet.

but, the scale shows the run is 1300 feet.

the grade on the east side would be

The population of a small rural town in the year 2006 was 2,459. the population can be modeled by the function below, where f(x residents and t is the number of years elapsed since 2006. f(t) = 2,459(0.92)
