Answer:
The System of equations :
[tex]40+2x=y \\4x=y[/tex]
Their expenses and sales both equal at selling 20 grams of links.
Step-by-step explanation:
Company spent on advertising = $40
Cost of production of 1 gram of links = $2
Let x be the no. grams of links produced by company
So, cost of production of x grams of links = 2x
So, Total cost of production of x grams of links=40+2x
Selling price of 1 gram of links = $4
Selling price of x grams of links = 4x
We are supposed to find What will their expenses and sales both equal.
So, [tex]40+2x=4x[/tex]
[tex]\Rightarrow 40=2x\\\Rightarrow \frac{40}{2}=x\\\Rightarrow 20=x[/tex]
So, Their expenses and sales both equal at selling 20 grams of links.
System of equations:
[tex]40+2x=y\\4x=y[/tex]
Refer the attached graph
[tex]40+2x=y[/tex] --- Blue line
[tex]4x=y[/tex]--- Green line
Hence The System of equations :
[tex]40+2x=y \\4x=y[/tex]
and Their expenses and sales both equal at selling 20 grams of links.
