Question 1024310
 On Tuesday, a local hamburger shop sold a combined total of 440
hamburgers and cheeseburgers. 
The number of cheeseburgers sold was three times the number of hamburgers sold. How many hamburgers were sold on Tuesday?
Equations:
h + c = 440
c = 3h
-------
Substitute for "c" and solve for "h":
3h + h = 440
4h = 440
h = 110 (# of hamburgers)
-----
c = 3h = 330 (# of cheesburgers)
