So in this question they want you to solve the equation for n.
25=5+.05n
First thing you want to do is subtract five from both sides giving you
20= .05n
next you want to finish getting n by itself by dividing both sides by .05 giving you this
400=n

The question was how many subscriptions did he sell. 400 is too much.
He sold 4 subscriptions.
25=5+.50n
25-5=20
20=.50n
20/.50=40
n=40
25=20/5.50
He sold 4 subscription
4/5.50= $22 got $3 tip
