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?

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
