Question

Elizabeth Oliver sells luxury cars. She earns a 4 percent straight commission. Lastmonth her sales totaled $128,000. What was her commission?

Answer 1

$128,000 represents 100%

To find how much is 4% we can use the next proportion:

`\frac{128,000\text{ \$}}{x\text{ \$}}=\frac{100\text{ \%}}{4\text{ \%}}`

Solving for x:

`\begin{gathered} 128,000\cdot4=100\cdot x \\ (512,000)/(100)=x \\ 5,120=x \end{gathered}`

Her commission is $5,120
