i guess her commission was $\$27$ so your job is to solve $.04x=27$ for $x$

You mean "plus 4% commission", right?

anonymous · Answer

yea plus 4% commission

mathstudent55 · Answer

The commission is $327 - $300 = $27
That $27 is 4% of her art sales.
Set up a proportion:
27 is to 4% as x is to 100%
27/4 = x/100
Now cross multiply and solve for x.
