Answer:
3x + 50 ≥ 100
At least 17 sales
Step-by-step explanation:
To solve this inequality you have to subtract 50 from both sides so 50 - 50 cancels out and 100 - 50 = 50
So now you have 3x ≥ 50, what you'll do is divided both by 3 so 3 ÷ 3 cancels out and 50 ÷ 3 = 16.6666 (repeating number)
x ≥ 16.6666 (repeating number) but since he cant make .6 of a sale you have to round that up to 17 sales.
So, the salesperson needs to make at least 17 sales to be paid at least 100
