WARRIOR [948]

Answer:

b = 2

Step-by-step explanation:

In order to find the value of b, we have to isolate b on one side of equation first

So,

3b+2(b-1)=8

Multiplying 2 with b-1

3b+2b-2=8\\5b-2=8

Adding 2 on both sides

5b-2+2=8+2\\5b=10

Dividing by 5 on both sides

\frac{5b}{5}=\frac{10}{5} \\b=2

Oksi-84 [34.3K]

When the insurance company want a plan with a deductible of $4,000, they need to charge a minimum of $18000 for premiums.

<h3>What is a deductible?</h3>

It should be noted that a deductible simply means the amount of money that is paid out of the pocket of the policy holder.

From the information given, each accident costs $18,000 on average. Therefore, this is the minimum amount of premium.

When they want a plan with a premium of $1,000, the amount that they'll need to charge for deductibles will be:

= (4000/18000) × 1000

= $220
