**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

then;

the expression which represents her earning =

**"At least" means **

**then;**

the sales necessary for the salesperson to earn at least $1000 in the one week

⇒

Subtract 320 from both sides we have;

**Divide both sides by 0.08 we get:**

**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 **

The answer is n equals five

Those two numbers are 30 and 12.

30+12=42

and

30*12=360

X = jane, y = jasmine, z = jocelyn

x + y + z = 56

x = 3z

y = 2z + 2

3z + 2z + 2 + z = 56

6z + 2 = 56

6z = 56 - 2

6z = 54

z = 54/6

z = 9 <==== jocelyn

x = 3z

x = 3(9)

x = 27 <=== jane

y = 2z + 2

y = 2(9) + 2

y = 18 + 2

y = 20 <=== jasmine
