Dakota and Cody sold a total of 16 items during their winter fundraising event. Cody sold four more than twice the number of items Dakota sold.
Formulate a system of equations that can be used to determine number of items Dakota sold, x, and Cody sold,
y, then solve the system using substitution. Check your work by graphing.
