In one week, your company takes in $2,220 in sales at its cell phone stores. The price breakdown per phone is as follows:
Cell phone model A4: $35
Smartphone Z20: $50

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.
Verify your results of the 2 linear equations by

ivettef365 · Answer

first equation you can have 
x = A4 PHONES
y = Z20 PHONES
so you have
x + y = 51

ivettef365 · Answer

the other equation you have is
35x + 50y = 2220

ivettef365 · Answer

now that you have 2 equations you can solve for x and y
