Four brothers each bought two hot dogs and a bag of chips at the football concession stand. If the bag of chips was $1.25, and the total was $18.20, which equation can be used to find the price of one hot dog?

Items bought in total:

4 brothers X two hot dogs and one bag of chips=

4X3=

12.

Hot dogs - x, chips - y.

4y + 8x = $18.20

Chips = $1.25 each so

4 ($1.25) + 8x = $18.20

5 + 8x = $18.20

8x = $18.20-5

8x = $13.20

x = $13.20/8 [13.20 divided by 8]

x = $1.65

This means that one hot dog = $1.65.

If you're unsure what to write as the answer I'd suggest that you put all the working out down in your copy/notes.
