The population of Bengal tigers in a region of India can be modeled by the function P = 450(0.85), where P is the population and I is the number of years since 2000.
What is the Bengal tiger population in 2000?
and by what percent does the tiger population decrease each year?

(a) The population in 2000 is 450

(b) 15% decreases each year

Step-by-step explanation:

Given

--- since 2000

Solving (a): The population in 2000

First calculate t

--- years since 200

So, we have:

Solving (b): Rate of population decrease

A function that decreases is represented as:

Where

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
