Hamburgers = h
Cheeseburgers = c
c = h + 54
h = h
The word problem states there was a total of 804 burgers sold, so this means we have to set up an algebra equation. See example below:
[tex]c + h = 804[/tex]
Now let's plug in the value of c:
[tex]h + 54 + h = 804[/tex]
Combine like terms:
[tex]2h + 54 = 804[/tex]
Isolate variable h:
[tex]2h = 804 - 54[/tex]
[tex]2h = 750[/tex]
Once again, isolate h:
[tex]\frac{2h}{2} = \frac{750}{2}[/tex]
h = 375.
Check your work and plug in values:
[tex]2(375) + 54 --> 750 + 54 = 804[/tex]
There were 750 hamburgers sold.
