Question

A certain computer loses half of its value every two years after how many years wI'll the computer be worth 12.5% of its initial value?

Answer 1

Answer: 3 years

Explanation:
1st year: 1.00*0.5=0.5
2nd year 0.5*0.5=0.25
3rd Year: 0.25*0.5=.125

Answer 2

A certain computer loses half of its value every two years

Suppose the initial value of the computer = $100

12.5% of its initial value = 12.5% * 100 = 0.125 * 100 = $12.5

Now we need to find in which year the value of the computer becomes $12.5

Initial value = $100

Computer loses half of its value every two years

After two years (second year )the value of computer = 100 divide by 2 = $50

After two years (fourth year )the value of computer = 50 divide by 2 = $25

After two years (sixth year )the value of computer = 25 divide by 2 = $12.5

So, after 6 years the computer be worth 12.5% of its initial value.
