Question

A salesperson at a furniture store earns a 3% commission on all sales. How much commission does the salesperson earn on a $1400 sale?
A) $21
B) $42
C) $420
D) $1,420

Answer 1

you can set up a proportion like this

\[\frac{ commission }{ total } = \frac{ percent}{ 100 }\]

\[\frac{ x }{ 1400 } = \frac{ 3 }{ 100 }\]

then you would cross multiply
