(1) Mr. Blake bought a Samsung Smart LCD 40-inch television for $45 000. After using it for two
years, she decided to sell it to her friend. She estimated a depreciation of 8% for the first year of
its used and a further 15% on its reduced value, for the sccond year.
(i) Calculate the value of Samsung Smart LCD 40-inch television the after two years.
(ii) Express the value of the stove after two years as a percentage of the original value.​

sorry not sure

step-by-step explanation:

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.

b

step-by-step explanation:

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
