So theres 4 hours and 60min equals 1 hour, so multiply 4 by 60 to get 240, so theres 240 minutes of time on the mp3. So 1/6 of that total time (240min) was on jazz, so what you do is divide 240 by 6 to get 40, so every 1/6 is 40min. So you could say he spend 40min listening to jazz, or you could say he spent 2/3 of an hour listening to jazz
So assuming simplet interest
find the change to find the interest
change=186000-129000=57000
simple interest=time times rate times principal
time is in years (8)
rate is in decimal
principal is amount invested (129000)
so
interest is 57000
57000=(8)(r)(129000)
57000=1032000r
divide both sides by 1032000
0.05523255813953488372093023255814=r
or
5.523255813953488372093023255814%
rounded
5.5%
Well 88 is 88% and 98% but if you round 88 would turn into 90% and 98 would become 100%. and 100% minus 90% is 10% so the broadcaster had about a 10% error.
I am sure not 100% right because i don't quite know percents yet.
So good luck.

The relationship between the two angles in the figure are congruent:)
The answer is a because you add the same variables and 5x stays the same
