On tuesday, a local hamburger shop sold a combined total of 336 hamburgers and cheeseburgers. the number of cheeseburgers sold was three times the number or hamburgers sold. how many hamburgers were sold on tuesday?

84 hamburgers!

(and 252 cheeseburgers -optional-)

Step-by-step explanation:

Write the following equations based on the problem:

H+C=336 <-- "combined total of 336"

C=3H <-- "the no. of Cheeseburgers sold was three times the no. of hamburgers"

1) Substitute 3H as C in the 1st equation:

H+3H=336

2) Combine alike terms:

4H=336

3) Divide both sides by 4:

H=84

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
