Answer:

V = 23,900(0.936)(0.936)(0.936)(0.936)

Step-by-step explanation:

AI-generated answer

The equation that represents the value of the car after 4 years is:

V = 23,900(0.936)(0.936)(0.936)(0.936)

Let's break it down step by step:

1. The initial value of the car is $23,900.

2. The car depreciates at a rate of 6.4% per year. This means that after each year, the car's value decreases by 6.4%.

3. To find the value of the car after 1 year, we multiply the initial value by 0.936 (100% - 6.4% = 93.6%).

4. To find the value of the car after 2 years, we multiply the value after 1 year by 0.936 again.

5. We repeat this process for 4 years, multiplying the value after each year by 0.936.

Therefore, the equation V = 23,900(0.936)(0.936)(0.936)(0.936) represents the value of the car after 4 years, taking into account the 6.4% annual depreciation rate.

Note: The other options given in the multiple-choice answers do not accurately represent the correct equation for calculating the value of the car after 4 years.

Answers

Simon will pay £18 in VAT for using 3000 units of electricity in one year.

The VAT rate for gas and electric is 5%.

Therefore, Simon will pay VAT on his electricity usage.

Let's calculate Simon's annual electricitycost without VAT:

Cost per unit of electricity = 12p

= £0.12

Number of units used in one year = 3000

Electricitycost without VAT = Cost per unit × Number of units

= £0.12 × 3000

= £360

Now, let's calculate the VAT amount:

VAT rate = 5% = 0.05

VAT amount = Electricitycost without VAT × VAT rate

= £360 × 0.05

= £18

Therefore, Simon will pay £18 in VAT for using 3000 units of electricity in one year.

If $11000 yields $1100 over 5 years, what is the interest rate?

Answers

Answer:

1.92449%

Step-by-step explanation:

Simple Interest Rate Formula: A = P(1 + r)ⁿ

Step 1: Define variables

Principle amount P = 11000

Total amount A = 11000 + 1100 = 12100

Years n = 5

Step 2: Substitute and Evaluate for r

12100 = 11000(1 + r)⁵

11/10 = (1 + r)⁵

1.01924 = 1 + r

r = 0.019245

Step 3: Convert to percentage

0.019245 × 100 = 1.92449%
