Based on the rental cost of the computer and the increase in the rent the next day, the rate of change was 37.5%.
<h3 /><h3>How to find the rate of change?</h3>
The rate of change simply refers to how the price of the rent of the computer had changed from the day that James rented it, to the next day.
The rate of change can be found by the formula:
= (New rental cost of computer - Rental cost to James) / Rental cost to James x 100%
Solving for the rate of change gives:
= (55 - 40) / 40 x 100%
= 15 / 40 x 100%
= 37.5%
