I was thinking that the answer could be

2.810; log3 21.903

OR

<span> 2.810; log3 55.2 </span>

So,<span> log5 of 92 is between 2.5 and 3 Correct answer is A</span>

\cfrac{8000}{53.0148852}\approx pymnt\implies 150.9010152318\approx pymnt$

Martha has $180. She needs a total of $2,000 to start investing in stocks. She earns $60 per day working, of which she saves $50

DIA [1.3K]

So she earns $60 per day working, but only saves $50. To solve this equation you have to multiply $50 to each day she works. If the total has to be exactly $2,000 then you must multiply 50 x 36.4 and that equals $2,000.
Your answer should be 36.4 days.
