On Thursday a local shop sold a combination of 417 hamburgers and cheese burgers. The number of cheeseburgers sold was two times

seropon [69]

Answer:

The number of hamburgers sold was 139 and the number of cheeseburgers sold was 278.

Step-by-step explanation:

Let

x -----> the numbers of hamburgers sold on Thursday

y -----> the numbers of cheeseburgers sold on Thursday

we know that

$x+y=417$ ----> equation A

$y=2x$ ----> equation B

Substitute the equation B in equation A and solve for x

$x+2x=417$

$3x=417$

$x=139$

Find the value of y

$y=2(139)=278$

therefore

The number of hamburgers sold was 139 and the number of cheeseburgers sold was 278.
