Answer:
$21,000
Step-by-step explanation:
If Ricky´s total sales last month were 150,000 and earns a commission of 14% that means extra money and by increasing money the 14% increase in money can go up by 100% because 100% would be the original amount
100%+14%=114%
114%*150,000=171,000
171,000-150,000=21,000
