Final answer:
To find the total cost of a t-shirt with a list price of $22 in a province with an 8% PST rate and a 5% GST rate, calculate the PST and GST separately and then add them to the list price.
Step-by-step explanation:
To find the total cost of the T-shirt with a list price of $22, we need to consider both the provincial sales tax (PST) and the Goods and Services Tax (GST). First, calculate the PST by multiplying the list price by the PST rate of 8%, which gives us $1.76. Then, add the PST to the list price to get the total before GST: $22 + $1.76 = $23.76.
Next, calculate the GST by multiplying the total before GST by the GST rate of 5%, which gives us $1.19. Finally, add the GST to the total before GST to find the final amount the consumer would pay: $23.76 + $1.19 = $24.95.
