The number of caps a new online store sells increases by a factor of 4 each month. the function f(x)=4^x represents the number of caps sold in month x. when does the store sell 64 caps? a.month 3 b.month 4 c.month 2 d.month 16

For this case we have the following variables:

x: number of months

f (x): number of caps sold

The function that models the problem is given by:

By the time the store sells 64 caps we have:

From here, we clear the number of months:

the store sells 64 caps in 3 monts

A. month 3

C

Step-by-step explanation:

First, multiply to , then to , after you have done that, you would get an equation looking like this:

Next, add and/or subtract the fractions with the variables together and the ones without together, and that is how you get to your final answer
