Question

Bethany paid $408.75 for a pair of diamond stud earrings. The sale price was $375. What is the Percent of Sales Tax she paid for the earrings? Please help me

Answer 1

She paid 9% of sales tax

Explanation:

The sale price of diamond = $375

Let x be percent of sales tax

So, amount of tax =
`x\% * 375 = (x)/(100) * 375 =3.75x`

So, Amount including tax = 375+3.75x

We are given that Bethany paid $408.75 for a pair of diamond stud earrings.

So, 375+3.75x=408.75

3.75x=408.75-375

`x=(408.75-375)/(3.75)`

x=9

Hence She paid 9% of sales tax
