a jeweler buys a ring from jewelry maker for $125. he marks up the price by 135% for sale in his store. what is the selling price of the ring with 7.5% sales tax?

Answers

Answer 1
Answer:

Answer with explanation:

Price paid by Jeweler to jewelry maker for a ring=$125

Price that Jeweler wants for the ring

          =125+125*(135)/(100)\n\n=125+168.75\n\n=293.75$

Sales tax =7.5%

Price of ring if 7.5 % sales tax is included in 135% marked price

      =293.75 -293.75 *(7.5)/(100)\n\n=293.75-22.03125\n\n=271.71875\n\n=271.72$

Price of ring if 7.5 % sales tax is not included in 135% marked price

      =293.75 +293.75 *(7.5)/(100)\n\n=293.75+22.03125\n\n=315.78125\n\n=315.78$

Answer 2
Answer: You wouls do 125 times 135% and that would be 168.75 then you would do 125 add 168.75 which would equal 293.75 then you would do 293.75 times 7.5% which equals 22.03 then you would do 22.03 add 293.75 and the answer would be 315.78

Answer:

A = ¹⁰⁷⁵/₁₆ = 67 ³/₁₆

Step-by-step explanation:

Area of a rectangle: A = b*h, where b = length of base and h = length of height

Plug in: A = 8 ¹/₄ * 10 ³/₄

Turn to improper fraction: A = ²⁵/₄ * ⁴³/₄

Multiply: A = ¹⁰⁷⁵/₁₆ = 67 ³/₁₆

Answer:

88   (11)/(16)

Step-by-step explanation:

The area of a rug is found by multiplying b*h. Just multiply 8 1/4 by 10 3/4 to get  88  11/16.

What is the solution to the following system? 4x+3y-z=-6 6x-y+3z=12 8x+2y+4z=6A. x = 1, y = –3, z = –1
B. x = 1, y = –3, z = 1
C. x = 1, y = 3, z = 19
D. x = 1, y = 3, z = –2

Answers

Answer:

Option B is correct.

Step-by-step explanation:

4x+3y-z= -6     eq(1)

6x-y+3z= 12     eq(2)

8x+2y+4z=6    eq(3)

We need to solve these equations and find the value of x, y and z.

Multiply equation 2 with 3 and then add equation 1 and 2

18x -3y +9z = 36

4x +3y -z = -6

_____________

22x + 8z = 30    eq(3)

Multiply equation 2 with 2 and add with equation 3

12x -2y + 6z = 24

8x +2y +4z = 6

____________

20x + 10 z = 30  eq(4)

Multiply equation 3 with 10 and equation 4 with 8 and then subtract

220x + 80z = 300

160x + 80z = 240

-        -            -

_________________

60x = 60

x= 60/60

x= 1

Putting value of x in equation 3

22x + 8z = 30

22(1) + 8z = 30

8z = 30 - 22

8z = 8

z = 8/8

z=1

Putting value of x and z in equation 1

4(1)+3y-(1)=-6

4 + 3y -1 = -6

3 + 3y = -6

3y = -6 -3

3y = -9

y = -3

so, Option B x=1, y=3 and z=1 is correct
