Should be 21 boys because 7+7+7 equal 21 and 3+3+3 equal 9 which equals 30

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

9966 [12]

Answer:

She paid 9% of sales tax

Step-by-step explanation:

The sale price of diamond = $375

Let x be percent of sales tax

So, amount of tax = $x\% \times 375 = \frac{x}{100} \times 375 =3.75x$

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

$x=\frac{408.75-375}{3.75}$

x=9

Hence She paid 9% of sales tax

Please Help What is the value of the expression? −34+(1/10÷2/5)

sweet-ann [11.9K]

Regarding your (1/10 divided by 2/5): I'm going to regard this as

(1/10) divided by (2/5).

First, write

1
---
10

Invert the fraction 2/5 and then multiply 1/10 by 5/2:

1(5)
-------- = 1/4, after reducing 5/10.
10(2)

Thus, <span>−34+(1/10÷2/5) yields -34 + 1/4, or -33 3/4.</span>
