In this question, we're calculating for the final price of the sweater.
We know that the original price of the sweater is $30
The price is reduced by 30%
Calculate the reduced price:
30 × 0.30 = 9
30 - 9 = 21
Now, calculate sales tax:
21 * 0.05 = 1.05
21 + 1.05 = 22.05
The total cost of the sweater is $22.05
Answer:
$22.05
