What is her commission and explain how u got it for brainliest and 30 points❤️

Hello there! What we know is that $7,500 were made in sales. The sales person earns 3% commission on her sales for the first $5,000. After that, it's 7.5% commission on sales. Let's subtract the sales from 5,000 to see what we get. 7,500 - 5,000 is 2,500. The sales person will earn 7.5% commission of the extra $2,500 she made. Let's start with the first part. To find commission, we subtract the sales by the percentage. 5,000 * 3% (0.03) is 150. Let's solve for the extra amount earned. 2,500 * 7.5% (0.075) is 187.5. So we found the commissions earned. Now, let's add the two amounts. 150 + 187.5 = 337.5. There. The sales person earned $337.50 in commission this month.
