Answer:

13 hamburgers

9 hotdogs

I see the person that also gave you an answer never explained how they got the answer. I thought you might like an explanation

Step-by-step explanation:

Let x = no. of hamburgers

y = no. of hotdogs

(1) x + y = 22 (2) 3.5x + 2.5y = 68

y = 22 - x 35x + 25y = 680

35x + 25(22 - x) = 680

35x + 550 - 25x = 680

10x + 550 = 680

10x = 130

x = 13 hamburgers

y = 22 - x = 22 - 13 = 9 hotdogs
