Question 100046
a salesman works on commission. if he receives $18.00 for selling a machine that cost $300, what is his commission rate?
Use the formula for finding percentage:
{{{(Part/Whote)}}} = {{{(Percent/100)}}}
.
{{{($18/$300)}}} = {{{(x Percent/100)}}}  [Plug-in the know variables and solve for the unknown variable]
.

(18)(100)=(300)(x%)  [cross-multiply]
.
1800=(300)(x%)
{{{((1800/300))}}} = {{{(300x/300)}}} [solve for (x %)]
6=x%
or
x=6%
.
Checking:
{{{(Part/Whote)}}} = {{{(Percent/100)}}}
{{{($18/$300)}}} = {{{(6 percent/100)}}}
.06=.06 [checks out]
