Answer 13

This question is a bit strange.
Up to step 3, the problem is 100% correct.
In step 4, decimals were written for the logs.
Step 4 may or may not be a mistake depending on whether an exact answer or an approximation is asked for.
Step 5 is definitely incorrect because the division of the decimals on the right side is incorrect.
If there is no choice of Step 5, then step 4 has to be the error, but I don't agree with the question.

Answer 14

@jammy987
On the first question, the question asks the rate of "decay"each month, which is a hint that the decay is cumulative, which accumulates over a year to give a depreciation of 6%, or 0.94 of the previous year.
Therefore we need to solve for k in
(1-k)^12=(1-0.06)
take the twelfth root on both sides,
(1-k)=(0.94)^(1/12)=0.994857
k=1-0.994857=0.005143.
Check:
(1-0.005143)^12=0.940000=depreciation of 6%
