In a densely populated metropolitan area, the number of households is 1,400,720. the number of households is increasing at a rate of 2.5% every year. select the correct equation that models the situation after t years.

Step-by-step explanation:

Hello, great question. These types are questions are the beginning steps for learning more advanced Algebraic Equations.

Fortunately there is already a formula that we can use for this situation. It is called the Exponential Growth Formula. With this formula you can calculate the amount of households after any amount of years. The Formula is the following,

Where:

Now we can customize the formula to model the current situation. Like so,

I hope this answered your question. If you have any more questions feel free to ask away at .

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:

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !
