3) Write an equation relating the minutes, x,
to the number of pages, y.

4) Use the equation in problem #3 to find the number of pages for 72 minutes.

Answer 1

3) y=3.5x

4) 3.5(72) = 252 pages for 72 min.

First we divide 21 by 6 to find the how many pages there is in 1 min. (we got 3.5) then we multiply (3.5) by the number of minutes (72) and we get 252 pages for 72 minutes.

Hope that helped:)
