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 already. How many more boxes must they sell to raise 180 dollars?
Answer: We are given:
The amount of money Tony's club get for every box they sell [tex]=1 \frac{1}{8} =1.125[/tex] dollar
They amount of money Tony's club has raised by selling 75 boxes is:
[tex]75 \times 1.125=84.375[/tex] dollars
The amount of money Tony's club is required to raise = 180 dollars
The remaining need to be raised is :
[tex]180-84.375=95.625[/tex] dollars
Therefore, the number of more boxes to be sold are:
[tex]\frac{95.625}{1.125}=85[/tex]
Hence, 85 more boxes they must sell to raise 180 dollars
