Question 1125480
.
<pre>
Use the proportion


{{{x/50000}}} = {{{(250/200)^4}}},


which is the same as


{{{x/50000}}} = {{{(5/4)^4}}},    or


{{{x/50000}}} = {{{625/256}}}.


From the last proportion,  find  x = {{{50000*(625/256)}}}.


Use your calculator.

Comment from student: I already tried solving this on my own, using a calculator as you suggested. 
I got an answer that looks very wrong however, and was hoping you would have provided your final solution 
so that I could cross reference. With your steps being much different than how I was taught, and no way to cross check, 
this doesn’t help me at all unfortunately. Thank you for your time regardless. Have a nice day.
