Three months ago, santos could walk 2 miles in 40 minutes. today he can walk 2 miles in 25 minutes. determine the percent of change. state whether the percent of change is am increase or decrease.

step-by-step explanation:

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)

the answer to your question is b.
