We know that
• There is a one-time payment of $57.32.
,• There is a weekly payment of $3.25 per sale.
,• The minimum payment you want to get is $195.
Based on the given information, we can form the following inequality
[tex]57.32+3.25w\ge195[/tex]Then, we solve for w (sales)
[tex]\begin{gathered} 3.25w\ge195-57.32 \\ 3.25w\ge137.68 \\ w\ge\frac{137.68}{3.25} \\ w\ge42.36 \end{gathered}[/tex]So, you need to make at least 43 sales. Observe that we can't take 42 sales as an answer because that way there wouldn't be enough money to reach the payments.
