Answer: She must sell at least 10
Step-by-step explanation:
Hi there,
The first step in solving this problem is to find out the difference is between the amunt she wants to earn and her base pay. 125 - 75 is 50, is she needs to make more than $50 from sales. Now, we have to divide 50 by how much she earns per sale, 5. Doing this we get 10, so she has to make more than 10 sales. This can be written as x > 10, where x is the number of sales.
Have a good day,
Jamie
