The bag contains 160 cups of feed.
If the dog eats 62 cups of feed per week, we can calculate how many weeks of feed does the bag contain by dividing 160 by 62:
[tex]\#\text{weeks}=\frac{160\text{ cups}}{62\text{ cups/week}}\approx2.58\text{ weeks}[/tex]
As she will be picking more feed in 2 1/2 = 2.5 weeks, and as 2.58 > 2.5, we know that the bag of feed will last until then.
Answer: Yes, it will last 2.58 weeks, that is greater than 2 1/2 weeks.
