A) The greatest number of museum tickets that can be sold for $21 is 14 tickets.
B) Use the equation below: Rise ÷ Run You can use (4 tickets, 6 dollars) as one point. You rise up by 6 dollars and run by 4 tickets so now you have to do rise÷run which is 6÷4. That means the answer is $1.50, so one ticket costs $1.50
C) c= total amount of money n= number of muesuem tickets bought
c=1.50n (I believe this is the right answer, I'm not too sure)
