Answer:
her total sales was $8958.3
Step-by-step explanation:
Let $x was the amount of her total sales.
It has been given that she is paid 245 per week plus a 12% commission on all sales.
12% commission on all sales which is x should be equal to 0.12x.
Hence, her weekly payment is given by
245 + 0.12 x
However, in the question it is given that her gross pay was $1320 last week. Therefore, we have the equation
![245+0.12x=1320](https://tex.z-dn.net/?f=245%2B0.12x%3D1320)
Subtract 245 from both sides
![0.12x=1075](https://tex.z-dn.net/?f=0.12x%3D1075)
Divide both sides by 0.12
![x=8958.3](https://tex.z-dn.net/?f=x%3D8958.3)
Therefore, her total sales was $8958.3
