Four friends went to a festival, where they each had to pay an entrance fee and buy tickets for each ride they went on.

The table below shows how much money each of them spent at the festival and the number of rides each went on.
Find the rate of change between each of the friends. Make sure to write each rate of change as a unit rate.

To find the rate of change for each friend, we need to divide the change in money spent by the change in number of rides.

For Friend 1:
Rate of change = (10.5 - 0) / (4 - 0)
= 10.5 / 4
= 2.625 dollars per ride

For Friend 2:
Rate of change = (15.75 - 0) / (7 - 0)
= 15.75 / 7
= 2.25 dollars per ride

For Friend 3:
Rate of change = (8.75 - 0) / (3 - 0)
= 8.75 / 3
= 2.9167 dollars per ride (rounded to 4 decimal places)

For Friend 4:
Rate of change = (|수 - 0) / (|수 - 0)
= |수 / |수
= |수 per ride

Without the values for Friend 4, it is not possible to calculate their rate of change.
