As a salesperson, you are paid $50 per week plus $2 per sale. This week you want your pay to be at least $100. What is the minimum number of sales you must make to earn at least $100?
+895 So you earn 50 plus 2 per sale. This is the same as the equation 2x+50.
To get the minimum number of sales necessary, set equal to 100.
\(2x+50=100\)
Subtract 50 from both sides.
\(2x=50\)
Divide both sides by 2.
\(x=25\)
So, to earn $100 a week, you have to make 25 sales.
+895 So you earn 50 plus 2 per sale. This is the same as the equation 2x+50.
