Answer 1

Answer:

b. It decreased by 25% every year.

Step-by-step explanation:

1. The first thing you do is write out the equation, which is y=95(0.75)t

2.You then make an equation that can help you find whether the rate is positive or not, in order to find out if the number of subscribers is decreasing.

-------------> y=95(1-0.25)

Then:

-------------> y=95(1+(-0.25))

This equation above shows that there will be a decrease of 25% every year.

ANSWER: b. It decreased by 25% every year.
