Alexis is working at her schools bake sale. Each mini cherry pie sells for $4 and each mini peach pie sells for $3. Alexis sells 25 pies and collects $84. How many pies of each kind does she sell?
Let each cherry pie be c and each peach pie be p. We have the following equations:
Substitution Rule
Elimination Rule
Cramers Rule
No matter which way you choose, you get c = 9 and p = 16.
