X = 7/8x + 4
x - 7/8x = 4
8/8x - 7/8x = 4
1/8x = 4
x = 4*8
x = 32
d = log₂p represents a logarithmic function, The expression log₂(10) tells us when the population reaches 10,000 and the equation 7 = log₂(128) tells us that the population reaches 128,000 in 7 days.
<h3>What is an
exponential function?</h3>
An exponential function is in the form:
y = abˣ
Where a is the initial value of y and b is the multiplication factor.
Let p represent the bacteria population in thousand after d days.
Since each day, the bacteria population grows by a factor of 2, hence:

Hence, d = log₂p represents a logarithmic function
The expression log₂(10) tells us when the population reaches 10,000 and the equation 7 = log₂(128) tells us that the population reaches 128,000 in 7 days.

Answer:
$84.38
Step-by-step explanation:
Assuming each member costs the same price, multiply by the fraction (6/4).
In other words, divide the total by 4 to get 1 person. Multipluy by 6 to see how much 6 people would cost.
56.25 x 6 = 337.5
337.5/4 = 84.375
