Depreciation A new car worth 25,000 deprecates at a rate of 50% every 3years the value of the car after 6 years is 25,000 (0.5^2) which of the following key stroke sequences is better for finding the cause of the car? Explain your reasoning

Answer:The answer is (b)Step-by-step explanation:To check this, we have to evaluate both options:Using option a:First we have to multiply 25000 and .5 because the in () has the highest priority :=> 25000 * .5 = 12500After that, we will square it:=> (12500)^2 = 156,250,000 that is way more than the actual value.So option (a) is wrong Using option b:First we would take square of .5 because of ():=> (0.5)^2 = 0.25After that, multiply it with 25,000=> 25000* 0.25 = 6250 That is the required answer
