Barney is an ecologist who studies the change in the tiger population of Siberia over time.
The relationship between the clapsed time t, in decades, since Barney started studying the population, and
the number of tigers. N(t), is modeled by the following function:
N(t) = 710(8/125)^t
Complete the following sentence about the rate of change in the tiger population. Round your answer to
two decimal places.
The tiger population loses 3/5 of its size every
decades.

Step-by-step explanation:

The collector has 160 movie posters and 120 band posters.

She wants to sell 24 movie posters but still have her poster collection maintain the same ratio of 160:120.

Total ratio = 160 + 120 = 280

If she sells 24 movie posters, it means

24 = 160/280 × x = 160x/280

Where x = total number of movie posters and band posters sold

24 × 280 = 160x

160x = 6720

x = 6720/160 =42

Number of band posters that she should sell = total number of both posters - number of movie posters.

Number of band posters that she should sell = 42-24 =18
