Answer: $8.19

Explanation:

Calculating the prices together yields

5.30 + 1.29 + 0.53 + 0.68 = 7.80

This figure represents the subtotal before tax. To compute the final sum after tax, we multiply by 1.05 to get

1.05*7.80 = 8.19

Alternatively, one can determine 5% of 7.80 which gives 0.05*7.80 = 0.39 as the sales tax, which is then added to the previous subtotal. This results in 7.80 + 0.39 = 8.19

Using the multiplier of 1.05 is useful when applying multiple percentage increases (it can also work with multiple discounts).

Answer:

$8.19

Step-by-step explanation:

1. First, sum the prices of all items together

5.3 + 1.29 + 0.53 + 0.68 = 7.8

2. Next, calculate 5% of the total item cost

5% = 0.05

7.8 · 0.05 = 0.39

3. Finally, add the sales tax to the initial item total

7.8 + 0.39 = 8.19
