Question

As a salesperson, you are paid $50 per week plus $3 per sale. This week you want your pay to be at least $110. What is the minimum number of sales you must make to earn at least $110?

Answer 1

20 sales.. 110 minus 50 dollars for a WEEKS pay leaves 60 divided by 3 dollars a sale leaves 20 sales

Answer 2

so 50 per week+3 times number of sales
represent s as number of sales
pay=50+3s
if you want pay to be at least 110 or pay<110 so
110>pay=50+3s
110>50+3s
treat as regular equation: do the saem to both sides so it will stay equal
also isolate the s term

110>50+3s
subtract 50 from both sides
60>3s
divide both sides by 3
20>s
you must make at least 20 sales
