Answer:
Tony needs to sell 85 more boxes to raise a profit of $180.
Step-by-step explanation:
We are given the following in the question:
Profit per box =
[tex]1\dfrac{1}{8}\text{ dollars}[/tex]
Number of boxes sold = 75
Profit earned on 75 boxes =
[tex]75\times 1\dfrac{1}{8}\\\\=\$84.375[/tex]
Total profit to be raised = $180
Amount of profit left to be earned =
[tex]=180 - 84.375\\=\$95.625[/tex]
Number of boxes to be sold to earn a profit of $95.625 =
[tex]=\dfrac{95.625}{\frac{9}{8}}\\\\=95.625\times \dfrac{8}{9}\\\\=85[/tex]
Thus, Tony needs to sell 85 more boxes to raise a profit of $180.
