Question

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?

Answer 1

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

Answer 2

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
