You can put this solution on YOUR website! Can you please help me? The problem is: The area of Lake Michigan is 9420 square miles less than the area of Lake Superior, which is about one-fifth the size of the Caspian Sea(about 150,000 sq mi.) Write and solve an equation to find the approximate area of Lake Michigan. Thanks!

Pull out information from the problem:
From: "Caspian Sea(about 150,000 sq mi.)":
Area of Caspian Sea = 150000 sq mi
.
From: "Lake Superior, which is about one-fifth the size of the Caspian Sea"
Area of Lake Superior = (1/5)(150000) sq mi
.
From: "Lake Michigan is 9420 square miles less than the area of Lake Superior"
Area of Lake Michigan = (1/5)(150000)-9420 (this is your equation)
.
To solve:
Area of Lake Michigan = (1/5)(150000)-9420
Area of Lake Michigan = 30000-9420
Area of Lake Michigan = 20580 sq mi
