I have another question, that I just want to make sure that I have the correct answer. @perl Can you check?

Answer 8

John is buying a gold chain that had an original price of $950 but is advertised as 45% off. Sales tax of 9.50% applies to the discounted price. How much will John pay for the chain?

Answer 9

I got the answer of $572. 14.

Answer 10

we have the same equation, but this time you multiply twice

Answer 11

original price = 950
discounted price = 950 * ( 1 - .45)
discounted price & sales tax = 950(1-.45) ( 1 + .095)

Answer 12

which is equal to 572.1375 ~ 572.14
I get the same answer as you

Answer 13
