Tony'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. How many more boxes do they have to sell to get 180 dollars?

Answer: they have to sell 85 boxes to get 180 dollars.

Step-by-step explanation:

Let x represent the number of boxes that they would sell.

For every box they sell, they get 1 1/8 dollars profit. Converting 1 1/8 dollars to decimal, it becomes 1.125 dollars. This means that if they sell x boxes, the amount of profit that they would make is 1.125x dollars.

They have sold 75 boxes. It means that the profit they made from selling 75 boxes is

75 * 1.125 = 84.375

Therefore, to get 180 dollars profit, the number of boxes they need to sell is

1.125x + 84.375 = 180

1.125x = 180 - 84.375

1.125x = 95.625

x = 95.625/1.125

x = 85
