Calvin mixes x pounds candy A that sells for $2.00 per pound with y pounds of candy B that costs $3.60 per pound to make 50 pounds of a candy mixture that costs $108. How many pounds of each kind of candy did he
use in the mix?

This problem can be modeled by the following system:
x + y = 50
2x + 3.60y = 108

What is the solution of this system? Put your answer in coordinates :)
