Real-Life Math -- Solution

You are collecting data in the Atlantic Ocean for environmental scientists. They want to figure out what is happening to the cod stocks and seal population in the area. You begin by monitoring the ocean water.

An iceberg is 12.5 percent above the surface. The iceberg you are measuring has 20 cubic feet above the surface. How many cubic feet are below the surface?

100 percent - 12.5 percent = 87.5 percent
87.5 percent of the iceberg is below the surface

If 12.5 percent = 20 cubic feet, then 87.5 percent = x cubic feet

Solve this ratio:

12.5 / 87.5 = 20 / x
12.5x = (87.5)(20)
12.5x = 1,750
x = 1,750 / 12.5
x = 140

The iceberg has 140 cubic feet under the surface of the water.
