On Thursday, a local hamburger shop sold a combined total of 327 hamburgers and cheeseburgers. The number of cheeseburgers sold
jeka94

Answer:

The number of hamburgers is 109.

Step-by-step explanation:

Let h = number of hamburgers

Let c = number of cheeseburgers

The total number sold gives us the equation below.

h + c = 327

"The number of cheeseburgers sold was two times the number of hamburgers sold.

This gives us the equation

c = 2h

Now we substitute c with 2h in the first equation and solve for h.

h + 2h = 327

3h = 327

h = 109

The number of hamburgers is 109.

Solve the system using substitution.
Alexeev081 [22]

Answer:

Option B that is (2,6) is correct

Explanation:

We have been given with system of equations

X+Y=8 and Y=3X

Here, we will substitute the value of Y=3X in X+Y=8

We will get X+3X=8

Further simplification we will get to 4X=8

Hence, the value of X=2

And now, substituting the value X=2 in Y=3X we will get Y=6.

Therefore, option B is correct.
