Answer 1

The website offers the better deal, saving $0.91 per tablet (Option b).

Step-by-step explanation:

To determine the better deal, we calculate the unit rate for each vendor. For the art supply shop, the cost per tablet is $10.26 / 9. For the website, it is £23.52 / 21. After converting £ to $ (using the exchange rate), we find the unit rate for the website (Option b).

The unit rate for the art supply shop is $10.26 / 9 = $1.14 per tablet. For the website, £23.52 * 1.35 / 21 = $1.23 per tablet. Comparing the two, the website offers the better deal as it has a lower unit rate, saving $1.23 - $1.14 = $0.09 per tablet.

To find the total savings for purchasing all tablets from the website, subtract the unit rate of the art supply shop from the unit rate of the website: $1.14 - $1.23 = -$0.09. Since the unit rate is negative, we take the absolute value to find the amount saved per tablet, which is $0.09.

In summary, the website offers the better deal, saving $0.09 per tablet compared to the art supply shop. The correct answer is (b) The website offers the better deal, saving $0.91 per tablet.
