Question

On Monp0day, a local hamburger shop sold a combined total of 324 hamburgrers and cheeseburgers. The number of cheeseburgers sold was three times the number of hamburgers sold. How many hamburgers were sold on Monday?

Answer 1

81 hamburgers

Step-by-step explanation:

Let the amount of hamburger sold be x

Let the amount of cheeseburgers sold be y

If a local hamburger shop sold a combined total of 324 hamburgrers and cheeseburgers, then;

x + y = 324 ... 1

Also, if the number of cheeseburgers sold was three times the number of hamburgers sold, then;

y = 3x ... 2

Substitute equation 2 into 1;

x+y = 324

x+3x = 324

4x = 324

x = 324/4

x = 81

Since x represents hamburger, hence 81 hamburgers were sold on Monday.
