At school barbecue 3 times as many hot dogs were served as Hamburgers. if there were 124
hot dogs and hamburgers served all together how many hot dogs were served

93 hot dogs

Step-by-step explanation:

Make a system of equations

Let x represent hamburgers and y represent hot dogs

x+y=124

y=3x

Substitute 3x in for y

x+3x=124

Combine like terms

4x=124

Divide by 4 on both sides

x=31

There were 31 hamburgers, sold, so plug 31 back in the first equation

31+y=124

Subtract 31 on both sides

y=93

So, 93 hot dogs were served

Hope this helps! :)
