At a baseball game, jose bought five hot dogs and three sodas for $17. At the same time, Allision bought two hot dogs and four sodas for $11. Find the cost of one hot dog and one soda.

Let d = cost of hotdog

Let s = cost of soda

5d + 3s = 17

2d + 4s = 11 Answer: d = $2.50

s = $1.50

Check: 5 (2.5) + 3 (1.5) = 17

12.5 + 4.5 = 17

17 = 17 2 (2.5) + 4 (1.5) = 11

5 + 6 = 11

11 = 11 I have done this problem befoore and this is how i work it out
