A certain computer loses half of its value every two years. If the value of the computer after 3 years is 425, what was the initial value of the computer

1,700      

Step-by-step explanation:

The computation of the initial value of the computer is shown below:

Let us assume the value of a certain computer in the first year is X

In the second year, it is

In the third year, it is

In the fourth year, it is

Now it is given that after 3 years, the value of the computer is = 425 i.e equal to

So, X = 1,700

Hence, the initial value of the computer is 1,700      

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
