### Question 2a:

### Question 2b:

a) What is the total cost that you will end up paying for the Chromebook?
b) What will your monthly payment be?

### Explanation:

1. **Calculating Discounted Price and Total Tax (Question 2a):**
   - **Original Price:** $499.99
   - **Discount:** 25%
     - Discounted amount = $499.99 * 0.25
     - Discounted amount = $124.9975
   - **Discounted Price:** $499.99 - $124.9975 = $374.9925
   - **Sales Tax:** 8%
     - Tax amount = $374.9925 * 0.08
     - Tax amount = $29.9994
   - **Total Price after Tax:** $374.9925 + $29.9994 = $404.9919

2. **Calculating the Total Cost and Monthly Payments (Question 2b):**
   - **Principal Amount (P):** $404.99
   - **Annual Interest Rate (r):** 6% or 0.06
   - **Monthly Interest Rate (i):** 0.06 / 12 months = 0.005
   - **Number of Payments (n):** 18 months

   - **Monthly Payment Calculation Using the Formula for an Amortizing Loan:**
     \[ M = P \times \frac{i(1+i)^n}{(1+i)^n-1} \]
     \[ M = 404.99 \times \frac{0.005(1+0.005)^{18}}{(1+0.005)^{18}-1} \]

   - **Total Cost Calculation:**
     - Total cost = Monthly payment * Number of payments

   - Note: Students can use a financial calculator or appropriate software to compute the values accurately.

These calculations illustrate how discounts

**Credit Card and Purchases Decision Making - Educational Exercise**

1. **Comparing Credit Card Costs:**

   You are trying to decide between 2 credit cards. Credit card A has no annual fee and an annual interest rate of 22.99%. Credit card B has an annual fee of $135 and an annual interest rate of 18.99%.

   What is the annual cost on a $2300.00 purchase?

   - **Card A:**
     $
   
   - **Card B:**
     $
   
   **Which card would you choose? Explain.**

2. **Price Calculation for a New Purchase:**

   You decide to purchase a new touchscreen Chromebook. The price is listed at $499.99 but the salesperson tells you that everything in the store is 25% off today. What is the total price that you pay for the Chromebook (including 8% Tax)?

**Instructions for Calculating Credit Card Costs:**

For both credit cards, you need to calculate the cost for an annual purchase amount of $2300.00, considering both the annual interest rate and any annual fees that may apply.

- Calculate the interest cost for each card by multiplying the purchase amount by the annual interest rate.
- For Credit Card B, remember to add the annual fee to the interest cost to get the total annual cost.

**Steps for Discount and Tax Calculation:**

To determine the final price of the Chromebook:

1. Calculate the discount amount by applying the 25% discount to the listed price of $499.99.
2. Subtract the discount from the listed price to get the discounted price.
3. Calculate the tax on the discounted price by applying the 8% tax rate.
4. Add the tax to the discounted price to get the total price.

**Example Calculation:**

- Original Price of Chromebook: $499.99
- Discount (25%): $499.99 * 0.25
- Discounted Price: Original Price - Discount
- Tax on Discounted Price (8%): Discounted Price * 0.08
- Total Price: Discounted Price + Tax

By following these instructions, you can determine which credit card is more cost-effective for your purchase and the total cost of the Chromebook after applying the discount and tax.
