at a concession stand three hot dogs and two hamburgers cost 7.00; two hot dogs and three hamburgers cost 8.00 find the cost of one hotdog and the cost of one hamburger
------
Equations:
3d + 2h = 7
2d + 3h = 8
-------
6d + 4h = 14
6d = 9h = 24
----
5h = 7
h = 7/5 = $1.40 (price of one hamburger)
-------------
Solve for "d"
2d + 3h = 8
2d + 4.2 = 8
2d = 3.8
d = $1.90 (price of one hot dog)
