Answer:
She sold for $4683.33
Step-by-step explanation:
For a sales of $1000 she is paid 7.5% which is equivalent to $75.
Since she earned $517 , her total sales was more than $1000.
Let she had a sales of $(1000+x).
Then her commission would be $75 + 12% of $x .
But her total commission was $517.
Then commission from sales after she sold for $1000 = $(517 - 75)
= $442
This is also equal to 12% of x.
x = $3683.33
Hence she sold for $4683.33
