Question 147822: Solve the system eqation by graphing. then classify the system as consistent or inconsistant and equation as dependent or independent.
What is the solution of the system equation?
3x + y =16
4x + 5y =14

B. Snookers lumber can convert logs into either lumber or plywood. In a given day, the mills turns twice as many units of plywood as lumber. It makes a profit of $20. on a unit of lumber and $50. on a unit of plywood. How many of each unit must be produced and sold in order to make a profit of $12480?
Snookers lumber must product and sell ?? units of lumber and ?? units of plywood in order to make a profit of $12480.

Quantitity EQUATION: P = 2L
-----------------
It makes a profit of $20. on a unit of lumber and $50. on a unit of plywood. How many of each unit must be produced and sold in order to make a profit of $12480?
Value EQUATION: 50P + 20L = 12480
---------------------------------------
Snookers lumber must product and sell ?? units of lumber and ?? units of plywood in order to make a profit of $12480.
---------------------
P - 2L = 0
50P + 20L = 12480
-----------------------------
50P -100L = 0
50P + 20L = 12480
----------------
120L = 12480
L = 104 (units of Lunber)
------------
P = 2L = 208 (units of plywood)
