Answer:
$33.60 is the correct answer.
Step-by-step explanation:
Price of the shirt = $40.00
discount rate = 20% or 20/100
so price of the shirt = 40 × 0.20 = 8
Shirt's price after 20% discount = 40 - 8 = $32.00
Now she paid 5% tax on the price after discount.
5% tax of 32.00
0.05 × 32 = $1.60
This amount will be added to his discounted price of a shirt.
= 32.00 + 1.60 = $33.60
Lydia pay $33.60 for the shirt.
