Kelly and 23 friends go roller skating. They pay a total of 186 dollars. About how much does it cost for one person to skate?

You need to figure out the unit rate so you need to:

1. divide 186 by 23 = 8.08695 ...

2. You only need to figure out the answer to the hundredth of a percent so you would round and get $8.09

3. The answer is $8.09

To do this first you must find the total number of people 23+1=24 so there are 24 people they paid 186 total divide this by 24 and you get 7.75 so each skate cost $7.75
