Given:
Last month sales = $900
Rate of commission = 20%
To find:
How much commission (in dollars) did she earn last month?
Solution:
We have, 20% rate of commission. So, the commission for the last month is equal to 20% of last month sales $900.
[tex]\text{Commission}=\dfrac{20}{100}\times 900[/tex]
[tex]\text{Commission}=20\times 9[/tex]
[tex]\text{Commission}=180[/tex]
Therefore, the commission for the last month is $180.
