Pennywise put $300 in a bank account earning 4% how much will he earn in interest

combine all like terms then its just a 2 step equation

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)

step-by-step explanation:

gym b charges $1.05 less per hour than gym a.
