since James has to use 4 inches of dental floss every day and he has a box with 16 yards, then, converting the 16 yards to inches we have the following:

[tex]\begin{gathered} 1yd=36in \\ \Rightarrow16yd=16(36)=576in \end{gathered}[/tex]

now we can divide the total inches by the 4 inches that James has to use every day:

[tex]\frac{576}{4}=144[/tex]

therefore, the box of dental floss should last 144 days
