A hamburger stand sells hamburgers for $3.87. In one day, the stand made $433.44. How

You write 5 1⁄2 pages of a report in 2 1/3 hours. What is the average number of pages you
write per hour?
6 answers
1) Use a proportion. Cross multiply and solve for x.
(5 1/2)/(2 1/3) = x/1
(2 1/3)x = 5 1/2
x = (11/2)/ (7/3)
x = (11/2) * (3/7)
x = 33/14 = 2.357 pages
2) You have two numbers. Do you think you should
add?
subtract?
multiply?
divide?

You would need to divide number 2 so I would say the end result is 112 hamburgers were sold.
