Dave found 16 coins on the sidewalk. They were made up of quarters and nickels. If Dave found $1.80, how many nickels were there?

OpenStudy (anonymous):

A quarter is one fourth of a dollar right? And a nickel? I need to know that to continue.

OpenStudy (anonymous):

Its 1/20 of a dollar i think

OpenStudy (anonymous):

OK. Let number of quarters be x. So number nickels = (16 - x). |dw:1341498703981:dw| Now solve for x.
