Rhonda bought a new laptop for $500. The laptop depreciates, or loses, 10% of its value each year. The

value of the laptop at a later time can be found using

the formula A - P(1 - 1)', where P is the original

value, r is the rate of depreciation written as a decimal,

and t is the number of years since it was purchased,

What will the laptop be worth in two years?

In two years, the laptop will be worth $.

The solution is ?

405

Step-by-step explanation:

A = P(1-r)^t

A = 500 (1-.1)^2

A = 500 (.9)^2

   = 500*0.81

   = 405

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:
