Answer:
B. 8 days
Explanation:
It takes 4 over 5 of a day to complete 1 over 10 of an order.
[tex]\begin{gathered} \frac{1}{10}\text{ of the order is completed in }\frac{4}{5}days \\ \text{Multiply both sides by 10} \\ \frac{1}{10}\times10=1\text{ } \\ \frac{4}{5}\times10=\frac{40}{5}=8days \\ 1\text{ order is completed in }8days \end{gathered}[/tex]At this rate, it will take 8 days to complete the entire order of sneakers.
