The square root is defined only for non-negative numbers. In other words, you can compute \sqrt{x} if and only if x \geq 0

If x \geq 0, the square root is a real number, and so is \sqrt{x}-4

Danielle earns a 8.25% commission on everything she sells at the electronics store where she works. She also earns a base salary
Mariulka [41]

Answer: her sales last week was $4300.

Step-by-step explanation:

Let x represent her her sales in a week.

Danielle earns a 8.25% commission on everything she sells at the electronics store where she works. This means that the commission she gets if she makes sales of $x is 0.0825x

She also earns a base salary of $675 per week. The expression for the total earnings for a week in which she made sales of $x would be

0.0825x + 675

if her total earnings for last week were $1,029.75, it means that

0.0825x + 675 = 1029.75

0.0825x = 1029.75 - 675

0.0825x = 1029.75 - 675

0.0825x = 354.75

x = 354.75/0.0825

x = $4300
