D

First year: 88 + 88 * 2.5% = 88 + 88 * 0.025 = 88 * 1.025
Second year: 88 * 1.025 + 88 * 1.025 * 2.5% = 88 * 1.025 + 88 * 1.025 * 0.025 = 88 * 1.025 * 1.025  = 88 * 1.025^2

Answer:

The population model of wolves after t years is given by

f(t)=88(1.025)^t

D is the correct option.

Step-by-step explanation:

The exponential function can be represented as

f(t)=a(1+r)^t

a = initial amount

r = rate

t = time

Now, we have been given that

r = 2.5% = 0.025

a = 88

On substituting these values in the above exponential model

f(t)=88(1+0.025)^t\\f(t)=88(1.025)^t

The population model of wolves after t years is given by

f(t)=88(1.025)^t

The first histogram has a large amount of cheaper books and doesn't have any books that are above $29.99. This histogram sells cheaper books. The second histogram sells a more even distribution of books by cost. There are no bins that are significantly higher than the rest. This second histogram sells more expensive books.

3rd pic:

The first set of data shows that the difference in the prices is very small while the second set of data shows a larger variety of prices. The first set represents its prices in equally divided groups making it easier to read and determine than the second set of data.
