Answer:
448.23
Step-by-step explanation:
Sales tax is addition to the original price
The original price is 100%
First we find 1% of this, which is 415.99 / 100 = 4.1599
Then multiply this by 7.75 = 32.239225
Add this to the original price = 415.99 + 32.239225 = 448.229225
You have to round this to an appropriate number as the question uses two decimal places I think this will suffice = 448.23
A couple are 5, 7, 17, 19, 23...
