Question

a local hamburger shop sold a combined total of 456 hamburgers and cheeseburgers. The number of cheeseburgers sold was three times the number of hamburgers sold. How many hamburgers were sold

Answer 1

h + c = 456
c = 3h

h + 3h = 456
4h = 456
h = 456/4
h = 114 <=== hamburgers sold

c = 3h
c = 3(114)
c = 342......cheeseburgers sold
