(1) The expected number of copies sold is 75
(2) The expected wage is $720
Explanation:
From the graph, we can see that x represents the number of copiers sold.
y represents the wages.
The equation of the graph is [tex]y=6x+120[/tex]
(1) Given that an employee earn $570.
We need to determine the number of copiers sold.
Let us substitute [tex]y=570[/tex] in the equation [tex]y=6x+120[/tex], we get,
[tex]570=6x+120[/tex]
[tex]450=6x[/tex]
[tex]75=x[/tex]
Thus, the number of copiers sold is 75
(2) Given that if an employee sells 100 copiers, we need to determine the expected wage.
Let us substitute [tex]x=100[/tex] in the equation [tex]y=6x+120[/tex], we get,
[tex]y=6(100)+120[/tex]
[tex]y=600+120[/tex]
[tex]y=720[/tex]
Thus, the expected wage is $720
