Answer:
$7.82.
Explanation:
Given original price of the items = $156.34.
Also we are given sale tax is of 5% of the original price given.
In order to find the sale tax, we need to covert 5% into decimal first and then multiply that decimal by original price of the item/
5% in decimal form could be written as 0.05.
Now, 5% of $156.34 = 0.05 × $156.34 = 7.817.
We can round it to 7.82.
Therefore, the sales tax of 5% on a purchase of $156.34 is $7.82.
