Question 800813
a hot dog and a soda cost $2.25 and two hotdogs and three sodas cost $5.25 find the cost of a hot dog and soda
------
Equations:
d + s = 225 cents
2d+3s = 525 cents
------------------------
Modify for elimination::
2d + 2s = 450
2d + 3s = 525
-----
Subtract and solve for "s":
s = 75 cents (cost of one soda)
-----
Solve for "d"::
d + s = 225
d + 75 = 225
d = 150 cents (cost of one hot dog)
