The correct option is option B: There were 6.27 times as many people who visited the aquarium on the 7th as on the first day.
What is exponential function?
The function which involves an exponent with a base so that the base is rises exponent times is called exponential function.
for example is f(x)=bˣ where b is base and x is exponent
Here it is given that
the following exponential equation:
y = A(b)ⁿ
where the following variables is defined as :
A: the initial number of customers applied
b: the rate of increase of the number of people applied every month
n: the number of months from the bank opened
Substituting values in the above exponential expression we have:
y = 64(1.3)⁷
y = 64*6.27
Therefore There were 6.27 times as many people who visited the aquarium on the 7th as on the first day.
