The table below gives the cost per person to buy tickets to an upcoming concert. Find the rate of change.
People Cost ($)
2
148
3 222
4 296
5 370
The rate of change can be determined by calculating the difference in cost for each additional person.
For example, to calculate the rate of change between 2 and 3 people, we subtract the cost for 2 people from the cost for 3 people: 222 - 148 = 74.
Similarly, for the rate of change between 3 and 4 people, we subtract the cost for 3 people from the cost for 4 people: 296 - 222 = 74.
And for the rate of change between 4 and 5 people, we subtract the cost for 4 people from the cost for 5 people: 370 - 296 = 74.
Therefore, the rate of change is $74 per additional person.
