A) $13.80
B) $14.40
C) $15.60
D) $16.20

Answer 1

To find the price of the t-shirt after the tax is added, multiply the original price by the tax rate and add the result to the original price. The correct answer is $13.80.

Step-by-step explanation:

To find the price of the t-shirt after the tax is added, we need to calculate 15% of $12 (the original price).

15% of $12 is calculated by multiplying 0.15 and $12 which gives $1.80.

Adding the tax of $1.80 to the original price of $12 gives us a total price of $13.80.

Therefore, the price of the t-shirt after the tax was added is $13.80.
