Question

As a salesperson, you are paid $50 per week plus $3 per sale. This week you want your pay to be at least $100. Write an inequality for the number of sales, s, you need to make and determine the minimum number of sales you need to make to meet your goal. (Type ALT 242 on your keyboard for the ≥ sign or ALT 243 for the ≤ sign).

Answer 1

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
