Answer:
Mark's comission last month was $450.
Step-by-step explanation:
From the information provided, you know that last month, Mark's total clothing sales were $1,500 and that he earns a 30% comission on his total sales, so you have to calculate 30% of $1,500 to determine his comission last month:
$1,500*30%=$450
According to this, the answer is that Mark's comission last month was $450.
