Answer:
1. Equation: [tex]P=90N+2,100[/tex]
2. Total pay if Henry sells 27 copies: [tex]4,530\$[/tex]
Step-by-step explanation:
1. The equation of the line in Slope-Intercept form is:
[tex]y=mx+b[/tex]
Where "m" is the slope and "b" is the y-intercept.
According to the information given in the exercise, his base salary is $2,100. So you can identify that:
[tex]b=2,100[/tex]
Since he makes an additional of $90 for every copy of he sells, you can identify that:
[tex]m=90[/tex]
Therefore, the equation that represents this situation is:
[tex]P=90N+2,100[/tex]
2. If he sells 27 copies, then:
[tex]N=27[/tex]
Substituting this value into the equation, you get that his total pay would be:
[tex]P=90(27)+2,100\\\\P=4,530[/tex]
