5.2.4 A P E X Math (coin problem) Equations:

Coin Value Formula:
V(t)=P(1 + r)^t

Coin A: V(t)=25(1 + r)^t
Coin B: V(t)=40(1 + r)^t
_
In this function, if the value of “r” were to increase, with the value represented by “P” also increase or stay the same? Why? Explain your answer using terms such as “rate of growth” and “initial value” in the context of the coin problem.

(I only need an explanation for the question I typed above, I included images to provide more context.)
