Computer

The computer was purchased 10000,-. Each year, the price of a computer depreciates always the same percentage of the previous year. After four years, the value of the computer is reduced to 1300,- How many percent was depreciated price of the computer each year?

Correct result:

p =  39.95 %

Solution:

10000q4=1300 10000(1+p/100)4=1300 (1+p/100)4=1300/10000  p=100(11300/100004)=39.95%10000 q^4 = 1300 \ \\ 10000 (1+p/100)^4 = 1300 \ \\ (1+p/100)^4 = 1300/10000 \ \\ \ \\ p = 100\cdot (1-\sqrt[4]{ 1300/10000 }) = 39.95 \%
