The answer is #$18+$2.16=$20.16#

Remember: #12%-=12/100#

You should calculate #12%# of #18# and add it up to #18# to find the new salary.

To calculate #12%# of #18#:

If you earn #$100# you would receive #$12# pay increase. But you earn #$18# so we don't know the increase (lets call it #k#)

Since #12%# is always #12%#:

#12/100=k/18#

#k = 18*(12/100) = (18*12)/100 = 216/100=2.16#

As you can see in this step, if you want to know #x# percent of something, you can just multiply something with #x/100#.

The answer is #$18+$2.16=$20.16#
