Kathy Parker's employer pays 65% of the total cost of her $5,489 health insurance premium. What is her biweekly deduction for th
zzz [600]

Answer:

$73.89

Step-by-step explanation:

We have been given that Kathy Parker's employer pays 65% of the total cost of her $5,489 health insurance premium.

This means Kathy pays 35% of her health insurance premium.

Let us find 35% of $5489.

\text{Amount of health insurance premium paid by Cathy per year}=\frac{35}{100}\times\$5489

\text{Amount of health insurance premium paid by Cathy per year}=0.35\times\$5489

\text{Amount of health insurance premium paid by Cathy per year}=\$1921.15

As we are asked to find Cathy's biweekly deduction for the insurance we will divide amount of premium paid by Cathy by 26 as biweekly is paid 26 times per year.

\text{Cathy's biweekly deduction}=\frac{\$1921.15}{26}

\text{Cathy's biweekly deduction}=\$73.89

Therefore, Cathy's biweekly deduction for the insurance is $73.89.

What is the value of x? <br> 64 68<br> (8x -12)<br> (2x + 18)
tamaranim1 [39]
(8x - 12) + 64 + 68 = 180
(A straight line equals to 180)
8x - 12 + 132 = 180
Combine liked terms
8x + 120 = 180
-120 on both sides
8x = 40
/8 on both sides
x = 5

(8x - 12)
8(5) - 12
40 - 12
28

(2x + 18)
2(5) + 18
10 + 18
28

Answer:
x = 5
