Question 1073598
.
A company manufactures both liquid crystal display (LCD) and cathode ray tube (CRT) color monitors. 
The cost of materials for a CRT monitor is $30, whereas the cost of materials for an LCD monitor is $130. 
The cost of labor to manufacture a CRT monitor is $60, whereas the cost of labor to manufacture an LCD monitor is $130. 
During a week when the company has budgeted $10330 for materials and $11560 for labor, 
how many LCD monitors does the company plan to manufacture?
~~~~~~~~~~~~~~~~~~~~~~~~


<pre>
Let x = the number of liquid crystal display (LCD),
and y = the number of cathode ray tube (CRT) color monitors.

Then you have these two equations

30*x + 130*y = 10330     (1)   (the cost of materials)
60*x + 130*y = 11560     (2)   (the cost for labor)

To solve them, subtract the equation (1) from the equation (2) as the first step.

You will get

30x = 11560 - 10330.
