Question

Can someone help me please?!?!!!!

Answer 1

Answer:

Part A = 3 years

Part B = $3400

Step-by-step explanation:

To find this, we can model the value of the computer as V = A(.5)^x, in which x is the number of years. To find how long it takes to get to 12.5%, we can ignore all but the exponential part of the function and set equal to the percentage.

.125 = (.5)^x

3 = x

To find the initial value of the computer, use the formula created and solve for A.

V = A(.5)^x

425 = A(.5)^3

425 = A(.125)

3400 = A
