you buy a new computer for $2100. the computer's value decreases by 50% annually. what will be the computer's value after 5 years? round to two decimal places.

The computer's value after 5 years is $65.63 .

Step-by-step explanation:

The decreasing exponential function is given by

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

As given

You buy a new computer for $2100.

The computer's value decreases by 50% annually for 5 years .

a = $2100

50% is written in the decimal form

= 0.50

r = 0.50

t = 5 years

Put all the value in the decreasing exponential function

y = $65.63

Therefore the computer's value after 5 years is $65.63 .

i believe that the slope of the line is -5
