Ony's club is selling oranges to raise money. For every box they sell, they get 1 1/8 dollars profit. They have sold 75 boxes already. How many more boxes must they sell to raise 180 dollars?

Here is the solution:

So for every 1 boxes = $1.125 (1 1/8)

They have sold 75 boxes already so, 75 x $1.125 = $84.375

Tony needs to raise $180 so, $180 - $84.375 = $95.625

Tony still needs $95.625 more, so $95.625/$1.125 = 85

Therefore, tony needs to sell 85 more boxes in order to reach $180.
