Question

On Friday, a local hamburger shop sold a combined total of 420 hamburgers and cheeseburgers. The number of cheeseburger sold was three times tge number of hamburgers sold. How many hamburgers were sold on Friday?

Answer 1

Answer:

315 hamburgers

Step-by-step explanation:

Because 3 times the amount of hamburgers were sold than the cheeseburgers, it is fair to say that 420 burgers is 4 times the amount of cheeseburgers sold.

That means that 420/4 = 105 cheeseburgers were sold.

That means that 105 * 3 = 315 hamburgers were sold.

Answer 2

The total number of hamburgers sold on Friday is 105

How to find the number of hamburgers sold on Friday?

Number of Hamburgers sold = h

Number of Cheeseburgers sold = c

h + c = 420

c = 3*h

substitute the value of c in  ( h + c = 420 )

h + 3h = 420

4h = 420

h = $\frac{420}{4}$

h = 105

The number of hamburgers sold is 105
