Will give medal! Eighty percent of a roof, or 2800 square feet of the roof, has been re-shingled. What is the total area of the roof? a. 22,400 sq ft b. 2240 sq ft c. 3500 sq ft d. 35000 sq ft

OpenStudy (abdullahm):

Let's call the total area of the roof x 80 percent of x is 2800 'of' in mathematics means multiplication 'is' in mathematics means equal 80% * x = 2800 Can you solve for x?

OpenStudy (ellerai):

would i turn 80 into a decimal then? to solve for x?

OpenStudy (ellerai):

??

OpenStudy (abdullahm):

You can do that. 80% = 0.8

OpenStudy (ellerai):

So it would be 3500
