Explanation:

Response
Question 9

Step1: Calculate total tax rate

Total tax rate = PST + GST = \( 8\% + 5\% = 13\% = 0.13 \)

Step2: Calculate tax amount

Tax amount = Cost of boots × total tax rate = \( 115 × 0.13 = 14.95 \)

Step3: Calculate total cost

Total cost = Cost of boots + tax amount = \( 115 + 14.95 = 129.95 \)

Step1: Calculate discount amount

Discount amount = Original cost × discount rate = \( 319.75 × 40\% = 319.75 × 0.4 = 127.9 \)

Step1: Calculate discount rate

New price rate = \( 100\% - 25\% = 75\% = 0.75 \)

Step2: Calculate new price

New price = Original cost × new price rate = \( 49.99 × 0.75 \approx 37.49 \)

Answer:

d. $129.95
