(15/100)n=1050
n=(1050)(100/15)
=7,000

15/100=1050/n <<<cross multiply
15n=105000 <<< divide by 15
n=7000 <<<answer
Its a proportion

whenever you see the word “of” in a question like this, multiply where the “of” is. 15% is the same as .15, so…
.15Xn=1050
——– —— divide both sides by .15
.15 .15
n= 7000
