Answer:
Here, x represents the weekly sale
As per the statement:
A salesperson earns $320 per week plus 8% of her weekly sales.
"8% of her weekly sales" means [tex]\frac{8}{100}x = 0.08x[/tex]
then;
the expression which represents her earning = [tex]320+0.08x[/tex]
"At least" means [tex]"\geq"[/tex]
then;
the sales necessary for the salesperson to earn at least $1000 in the one week
⇒[tex]320+0.08x\geq 1000[/tex]
Subtract 320 from both sides we have;
[tex]0.08x\geq 680[/tex]
Divide both sides by 0.08 we get:
[tex]x\geq 8500[/tex]
Therefore, the sales necessary for the salesperson to earn at least $1000 in the one week is: greater than or equal to $8500 i.e [tex]x\geq 8500[/tex]
