Answer:

#104%=312#

Explanation:

Well to start off, with any given number we can say it is #100%#.

#therefore# #300=100%#

Therefore, we can find out that if we divide by #100#, we can get #1%#

#300=100% -> 3=1%#

Therefore we can figure out #4% = 4 xx 1%#, therefore we multiply the value of #1%# by #4#

#4%=4 xx 1% -> 4xx3=12#

#therefore# #4%=12#

But we want an INCREASE in #4%# therefore we add this on.

#104%=300+12 -> 312#

#104%=312#
