how many hamburgers were sold on thursday

Question

A local hamburger shop sold a combined total of
763
hamburgers and cheeseburgers on Thursday. There were
63
more cheeseburgers sold than hamburgers. How many hamburgers were sold on Thursday?

Answer 1

Let h = hamburger and c = cheese burgers

Here's what we know:

h + c = 763

c = h + 63

 

We have a value for c, so let's plug it in:

h + (h + 63) = 763

Simplify"

2h + 63 = 763

Subtract 63 from both sides:

2h = 700

Divide by 2:

h = 350

 

Check:

c = 350 + 63

413

350 + 412 = 763

763 = 763
