On the field trip, abbey, bethany, christine, and darcy bought a total of 4 hot dogs and 3 sodas, which cost the girls $17.00. edward bought 2 hot dogs and 1 soda from the same lunch stand and it cost him $7.80 before tax. how much would one hotdog and one soda cost before tax?

6.30$

Step-by-step explanation:

If you add 7.80$ and 7.80$ that come to 4 hot dogs,

The rest of the money is how much one soda cost ( 2.40$ ),

Dividing that 7.80$ by 2, To only have one hot dog, would put you at

3.90$ fro one hot dog, then all you have to do is add them together, to get the total of 6.30

 7.80   |     17.00      |    7.80/2  |    2.40

+ 7.80  |    - 15.60     |    3.90     |  + 3.90

15.60   |   2.40          |                |   6.30
