Answer:
$8,000
Step-by-step explanation:
Let minimum amount she needs to sell = x
Commission rate = 7.5%
Amount of commission = $600
7.5% of x = 600
7.5/100 * x = 600
0.075 * x = 600
0.075x = 600
x = 600/0.075
= 8,000
x = $8,000
The minimum amount she needs to sell in order to earn $600 if she earns a 7.5% commission on everything she sells is $8,000
