A local hamburger shop sold a combined total of 577 hamburgers and cheeseburgers on Thursday.
There were 73 fewer cheeseburgers sold than hamburgers. How many hamburgers were sold on Thursday?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
What you are given is this:
h + c = 577, (1) (h = # of hamburgers, c = # of cheeseburgers)
h - c = 73. (2)
Add equations 1) and (2) (both sides). You will get
2h = 650. Hence, h = = 325. This is the number of hamburgers sold.
Now find yourself the number of cheeseburgers.
