Answer:
Total sales= 10000
Step-by-step explanation:
Given data
monthly salary=$1500
commission on total sales= 5.75%
gross pay=$2,075
Firstly, let us deduct the salary
2075-1500=$575
so Saiah earned a commission of $575
let the total sales be x
so 5.75% of x= $575
5.75/100*x=576
0.0575x=575
x=575/0.0575
x=10000 sales
