Answer:

b2 = 5

Step-by-step explanation:

16 = 1/2 x 4 (3 + b2)

16 = 2 (3 + b2)

16 = 6 + 2b2

16-6 = 2b2

10 = 2b2

10/2 = 2b2/2 (the 2s canceled out)

5 = b2

TEA [102]

Answer:

$24166.67

Step-by-step explanation:

$25 per hour and works 35 hours per week

Norma Jean makes 35 * 25  (<em>without sales) = </em>$875

<em> </em>Total commission made by Norma<em> </em>= 4500-875 = $3625

<em>let total number of sales by Norma be x</em>

15% is the same as 15/100

<em>so </em>(15/100) * x =3625 <em> multiplying both sides by 100</em>

15x = 362500<em> making x subject of formula</em>

x = 362500/15

x = 24 166.67

Norma should sell total items worth $24166.67
