Question

During a busy day, a food vendor sold 197 hot dogs and hamburgers. If he sold 43 more hot dogs than hamburgers, how many hot dogs did he sell?

Answer 1

Explanation:

System of equations

Let x = hotdogs and y = hamburger

x + y = 197

x = y + 43

Let's substitute the second equation into the first

(y+43)+y=197

2y = 197-43

2y = 154

y = 77 hamburgers

Now to subtract

197-77 = 120 hotdogs
