Writing Inequalities
As a salesperson you are pain $50 a week plus $3 per sale. If you want to make at least $100, write an inequality to solve for the number of sales you need to make.
Determine variable
x = number of sales
Pay = 50 + 3x
Want Pay to be greater than $100
100 ≤ 50 + 3x
Subtract 50 from both sides
50 ≤ 3x
Divide by 3
x ≥ 16.67 sales
Must make 16 sales in order to make more than $100
Check work
17(3) + 50 = $101.00
