**Homework Help: Questions and Answers:** Tommy is planning to buy a tablet for accessing learning materials on Vodacom E-school and KZN funda portal. He noticed an advertisement for a tablet on an online store.

**Details:**

Product: Amazon Kindle Fire 7” Tablet 16GB WiFi

Price: R 1,999

Shipping: 3 – 5 work days

Rating: 3.3 (based on 7 reviews)

- Explain the meaning of 16GB in the above context.
- Determine the price of the tablet excluding Vat, rounded off to 2 decimal places.
- The salesperson claims that the Vat charged on the tablet is approximately 7,7 times the total price of the tablet. Verify if the above claim is valid.
- If Tommy buys the tablet online, calculate the probability as a percentage that it will not be shipped in 5 work days.

**Answer:**

Let’s solve the problem step by step:

**1. Explain the meaning of 16GB in the above context.**

**16GB**refers to the storage capacity of the tablet. It indicates that the Amazon Kindle Fire tablet has 16 gigabytes of internal storage. This storage can be used to save apps, documents, music, videos, and other files. Part of this storage is used by the system software, so the actual space available to the user will be slightly less than 16GB.

**2. Determine the price of the tablet excluding VAT, rounded off to 2 decimal places.**

To calculate the price of the tablet excluding VAT (Value Added Tax), we’ll use the following formula:

Price Excluding VAT = Price Including VAT / (1+ (VAT Rate / 100) )

Assuming the VAT rate is 15% (standard VAT rate in South Africa):

Price Excluding VAT = R1,999 / (1 + (15/100)) = R1,999 / 1.15

Price Excluding VAT ≈ R1,738.26

**3. The salesperson claims that the VAT charged on the tablet is approximately 7.7 times the total price of the tablet. Verify if the above claim is valid.**

First, calculate the VAT amount:

VAT Amount=Price Including VAT − Price Excluding VAT = R1,999 − R1,738.2

Next, check if the VAT amount is 7.7 times the total price of the tablet:

7.7 × Total Price = 7.7 × R1,999 = R15,392.30

Since R260.74 ≠ R15,392.30, the salesperson’s claim is **not valid**.

**4. If Tommy buys the tablet online, calculate the probability as a percentage that it will not be shipped in 5 work days.**

The tablet will be shipped within 3 to 5 work days, so the probability that it will be shipped within 5 workdays is 100%. The probability that it will not be shipped within 5 workdays is 0%.

Therefore, the probability as a percentage that it will not be shipped in 5 workdays is **0%**.
