a salesperson earns $320 per week plus 8% of her weekly sales. the expression representing her earning is 320 + 0.08x. which of the following describes the sales necessary for the salesperson to earn at least $1000 in one week

X>=8,500 is the answer

The expression 320 + 0.08x shows the earning of a salesperson for her weekly sales.

To earn at least $1000, we have:

320 + 0.08x > = 1000

Subtracting 320 from both sides, we get:

0.08x > = 680

Now we need to Divide the above expression by 0.08 both sides,

So, we get:

x > = 8500

Therefore, to earn at least $1000 in one week, the salesperson needs the sales of greater than or equal to $8500.
