please help A salesperson earns a salary of $800 per month plus 2% of the sales. Which inequality represents the total sales if the salesperson is to have a monthly income of at least $1600?

x - the total sales
800 + 0.02 x ≥ 1600
0.02 x ≥ 1600 - 800
0.02 x ≥ 800
x ≥ 800 : 0.02
x ≥ 40,000
The total sales must be at least $40,000.
Let x= total sales per month

800 + 0.02x ≥ 1600
800 + 0.02x - 800 ≥ 1600 -800
0.02x ≥ 800
0.02x/0.02 ≥ 800/0.02
x ≥ 40000 USD 

The monthly total sales should be greater than or equal to 40000 dollars to have a monthly income of at least 1600 dollars.
