1. You decide to take out a car loan for $4000 at a simple interest rate of 4.6 % each year. Assuming you don't pay
    any of it back, how much money do you owe after 5 years?

Verified Answer :

Sure, let's solve this step by step.

To find out how much money you owe after 5 years with simple interest, we'll use the simple interest formula:

\(\[ \text{Simple Interest (I)} = \text{Principal (P)} \times \text{Rate (R)} \times \text{Time (T)} \]\)

where:
- \(\( P \)\) is the principal amount (initial loan amount)
- \(\( R \)\) is the annual interest rate in decimal form
- \(\( T \)\) is the time period in years

Given:
- \(\( P = 4000 \)\) dollars
- \(\( R = 4.6\% = \frac{4.6}{100} = 0.046 \)\)
- \(\( T = 5 \)\) years

First, let's calculate the simple interest:

\(\[ I = P \times R \times T \]\)
\(\[ I = 4000 \times 0.046 \times 5 \]\)

Now, we calculate step by step:
\(\[ 4000 \times 0.046 = 184 \]\)
\(\[ 184 \times 5 = 920 \]\)

So, the interest \(\( I \)\) accrued over 5 years is \(\( 920 \)\) dollars.

Next, we need to find the total amount owed after 5 years. This is the sum of the principal amount and the interest:

\(\[ \text{Total Amount Owed} = P + I \]\)
\(\[ \text{Total Amount Owed} = 4000 + 920 \]\)
\(\[ \text{Total Amount Owed} = 4920 \]\)

Therefore, after 5 years, you owe \(\( 4920 \)\) dollars.
