You can put this solution on YOUR website! Mark can type 45 words a minute. and there are 450 words per page.
1 min = 45 words
10 min = 450 words = 1 page
--------------------------------
At this rate, how many hours would it take Mark to type a paper x pages long?
x pages in 10x minutes = (10x/60) = (1/6)x hours

Tickets to a PLAY ARE $2 FOR STUDENTS AND $4 FOR ADULTS. a TOTAL OF 250 TICKETS WERE SOLD. iF S IS THE # OF STUDENT TICKETS SOLD, WHICH OF THE FOLLOWING IS A FORMULA FOR THE TOTAL SALES IN DOLLARS.
