Answer:

There were 275 computers

Explanation:

Computers replaced = total computers * percent replaced

What do we know?

The percent replaced is 20 = .2

55 computers were replaced.

Substitute this in

55 = total computers * .2

Divide each side by .2

55/.2 = total computers *.2 /.2

275 = total computers

There were 275 computers
