3 is the number that represents the rate of change, and 30 is the number that represents the amount of money that Kevin started with.

Step-by-step explanation:

Well for me it's simple, if you know that "h" represents "hours", and we know that we will have to multiply 3 into "h" to solve the equation, this will eventually change things, keyword change, so we now know that 3 represents the rate of change, and since 30 is the only number left, 30 is the amount of money Kevin started with.
