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?
Set up the inequality where s is the amount of sales you make:
50 + 2s >= 100
We use >= because the phrase at least 100 means 100 or more
Subtract 50 from each side:
2s >= 50
Divide each side by 2
s >= 25
