does any one know how to solve this problem for graphing in algebra in worded problem solving

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

Suppose that a total of 51 phones were sold.

amistre64 · Answer

its a system of equations if i read it right

anonymous · Answer

yes that is correct

amistre64 · Answer

you wanna know the number of phones sold?

anonymous · Answer

yes in a graph

amistre64 · Answer

well

graph:  x + y = 51
graph: 35x +50y = 2220

and see where they cross perhaps?

anonymous · Answer

I tryed that

anonymous · Answer

and they did not cross the graph said it was x only

amistre64 · Answer

#A4 = (2220 - 51(50))/(35-50) = 22

amistre64 · Answer

it graphs out right; 22 and 29

anonymous · Answer

humm when I graphed it  showed -0 and 2220 on the x axis

amistre64 · Answer

chk yout techniques :)

amistre64 · Answer

yout ..your

anonymous · Answer

I an supposed to find the x and y on the graph  and don't know how

anonymous · Answer

and I did check my math

amistre64 · Answer

when you graph the 2 equations; they cross at a common point; look at the site i posted for the picture.
