ms.amodei made four of her credit car payment late and fined four fees.The total change to her bank account from paying the late fees was -40.how much was one late fee

75 gophers (about)

Step-by-step explanation:

We will use continuous compounding interest formula:

Where

P(t) is final value (at time t)

P_0 is initial value

r is the compounding rate

t is the time period

Given:

P(t) = 78

r is 1.5% or 1.5/100 = 0.015

t is 3

We solve for P_0, what we want, using algebra as shown below:

So, the initial population was 75 gophers.
