The population of the world in 1987 was approximately 5 billion and the annual growth rate was estimated at 2 percent. If the world population followed an exponential growth model, find the projected world population in 2015. Round your answer to the nearest tenth of a billion. billion people

what?

step-by-step explanation:

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:

1. 22

2. 1

3. 7

4. 18
