Take -5x + 3x = -2x

because there is a -3x and a 3x they cancel each other out.

and the -17 is left

-2x = -17

divide -2 by -17 = 8.5

-3x-3(-5x-17)=3
-3x+15x+51=3
12x=48
x=3

If y is equivalent to an equation you can substitute that equation in for the y variable in the other equation bc they have the same value. Which it what I did.

Annual insurance is 1,000 face value.
satela [25.4K]

Answer:

The correct answer is A.

Step-by-step explanation:

  • Premium for Company A :

face value = 1.86 , charges are 20% more for smokers

⇒ Charges = 20% of 250000 = $50000

Total charge = Charge × face value

                     = 50000 × 1.86 = $93000

  • Premium for Company B :

face value = 1.86 , charges are 18% more for smokers

⇒ Charges = 18% of 250000 = $45000

Total charge = Charge × face value

                     = 45000 × 1.86 = $83700

  • Premium for Company C :

face value = 2.07 , charges are 25% more for smokers

⇒ Charges = 25% of 250000 = $62500

Total charge = Charge × face value

                     = 62500 × 2.07 = $129375

  • Premium for Company D :

face value = 2.25 , charges are 15% more for smokers

⇒ Charges = 15% of 250000 = $37500

Total charge = Charge × face value

                     = 37500 × 2.25 = $84375

Hence, The option A. is correct that is Aaron is paying the smallest premium possible with company B
