total cost of items with tax

Explanation:

Step1: Calculate discounted price for Item 1

Original price: $299.99, Discount: 30% = 0.3.
Discounted price = \( 299.99 \times (1 - 0.3) = 299.99 \times 0.7 = 209.993 \approx 209.99 \)

Step2: Calculate discounted price for Item 2

Original price: $34.00, Discount: 40% = 0.4.
Discounted price = \( 34.00 \times (1 - 0.4) = 34.00 \times 0.6 = 20.40 \)

Step3: Calculate discounted price for Item 3

Original price: $299.99, Discount: 20% = 0.2.
Discounted price = \( 299.99 \times (1 - 0.2) = 299.99 \times 0.8 = 239.992 \approx 239.99 \)

Step4: Calculate discounted price for Item 4

Original price: $16.00, Discount: 15% = 0.15.
Discounted price = \( 16.00 \times (1 - 0.15) = 16.00 \times 0.85 = 13.60 \)

Step5: Calculate total cost of items

Total = \( 209.99 + 20.40 + 239.99 + 13.60 = 483.98 \)

Step6: Calculate sales tax (8% = 0.08)

Tax = \( 483.98 \times 0.08 = 38.7184 \approx 38.72 \)

Step7: Calculate total cost with tax

Total with tax = \( 483.98 + 38.72 = 522.70 \)

Answer:

The total cost of items with tax is $\boldsymbol{522.70}$.
