Question

What will be the value in 5 years?

Answer 1

The equation for interest also works for depreciation 

the price drops by 11%
or the price of the machine next year would be 89% of this year

the initial price is 60,000
the amount of years is 5
and the percentage of next year is 89

the full equation would be 
60,000(0.89)^5

the price of the machine after five years is 33504.356694 (not rounded)
the answer you are looking for is C.

Answer 2

$c = s.i \times r \times t$
$s.i = 60000 \times \frac{11}{100} \times 5$
600× 55 = 33000.
