Answer: 5%
Step-by-step explanation:
Given that:
Ticket price of jacket = $199
Final price after addition of sales tax = $208.95
Percentage sales tax on the jacket =?
Final price after addition of sales tax = price of jacket + amount of sales tax paid
208.95 = 199 + amount of sales tax paid
amount of sales tax paid = 208.95 - 199
amount of sales tax paid = $9.95
Let Percentage of sales tax = x
(x / 100) * 199 = 9.95
199x / 100 = 9.95
199x = 995
x = 5
Hence percent sales tax paid = 5%
