at a bakery the cost of one cupcake and 2 slices of pie is $12.40. the cost of 2 cupcakes and 3 slices of pie costs $20.20. what is the cost of one cupcake?
Let the number of cupcakes be c
Let the number of pie slices be p
Total Cost = Unit cost * quantity
So we're given two equations:
No matter which method we choose, we get the same answer:
Let the number of cupcakes be c
Let the number of pie slices be p
Total Cost = Unit cost * quantity
So we're given two equations:
- 1c + 2p = 12.40
- 2c + 3p = 20.20
No matter which method we choose, we get the same answer:
- c = 3.2
- p = 4.6
