Question 661475: Westlake has 1600 public payphones. Three-fourths of the phones have dials. If one-third of the dial phones are replaced by push-button phones, how many dial phones remain? Answer by ReadingBoosters(3246) (Show Source):
You can put this solution on YOUR website! 3/4(1600) = 1200 = dials
1/3(1200) = 400 = replaced
1200 - 400 = 800 dials not replaced or remaining.
