Answer:

❤️❤️The organisers of an essay competition decide that a winner in the competition gets a prize of $100 and a participant who does not win gets a prize a $25. The total prize money distributed is $3000. Find the number of winners , if the total number of participants Let +x+ = the number of winners

+63+-+x+ = the number of non-winners

-----------------------------------

given:

+100x+%2B+25%2A%28+63+-+x+%29+=+3000+

+100x+%2B+1575+-+25x+=+3000+

+75x+=+3000+-+1575+

+75x+=+1425+

+x+=+19+

and

+63+-+x+=+63+-+19+

+63+-+x+=+44+

------------------

There are 19 winners

----------------------

check:

+100x+%2B+25%2A%28+63+-+x+%29+=+3000+

+100%2A19+%2B+25%2A44+=+3000+

+1900+%2B+1100+=+3000+

+3000+=+3000+
