Cell phone model A4: $35
Smartphone Z20: $50

Suppose that a total of 51 phones were sold.
Set up the system of equations that needs to be solved to determine how many of each type of phone were sold. Give a clear definition of the variables in the system.
Solve the system of equations, showing clearly how the solution was determined, and state the results clearly in light of the real-world situation.

Explanation / Answer

x is the number of cell phones sold y is the number of smart phones sold x + y = 51 35x + 50y = 2,220 Solve and you get 22 cell phones sold and 29 smart phones sold
