There was 420 hamburger and cheeseburgers. The cheeseburgers sold two times then the hamburger. How many hamburgers were sold

madam [21]

The answer is 140.

If there are 140 hamburgers sold, and there were 2x as many cheeseburgers sold, that adds up to 420.

140 x 2 = 280 (Cheeseburgers)
So there were 280 cheeseburgers sold.

280 (Cheeseburgers) + 140 (Hamburgers) = 420 altogether.

Hope this helps!
