William works at a nearby electronics store. He makes a commission of 6% percent on everything he sells. If he sells a computer

Naddika [18.5K]

Commission earned by William is $ 45.84

<h3><u>Solution:</u></h3>

Given that,

William makes a commission of 6% percent on everything he sells

He sells a computer for $764.00

<em><u>To find: Commission amount of William</u></em>

Given that he makes a commission of 6 % on everything he sells. So he has received a commission of 6 % of $ 764.00

Commission amount of William = 6 % of $ 764.00

a % of b can be written in fraction as $\frac{a}{100} \times b$

$6 \% \text { of } 764=\frac{6}{100} \times 764=0.06 \times 764=45.84$

Thus commission earned by William is $ 45.84
