In a week, 17 hens laid 85 eggs. what is the unit rate for eggs per hen?

The unit rate is 5. 

Here's why:
17 is a multiple of 85. To find the unit rate of eggs for 1 hen, you divide 85 divided by 17 which equals 5. So, for every 1 hen there are 5 eggs layed.

I hope this helps:)

What are the options
