Ray industries bought a touch screen monitor for $1200. it is expected to depreciate at a rate of 25% per year. what will the value of the monitor be in 3 years? round to the nearest dollar.

Value of the monitor be after 3 years is $506.25 .

Step-by-step explanation:

As the exponential decrease function is written in the form .

Where a is the intial value , r is the rate of interest in the decimal form and t is the time .

As given

Ray Industries bought a touch screen monitor for $1200. It is expected to depreciate at a rate of 25% per year.

a = $1200

25% is written in the decimal form .

= 0.25

r = 0.25

t = 3 years

Put all the values in the above

y =  $506.25

Therefore the  value of the monitor be after 3 years is $506.25 .

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3

ou would have 12 of each
