Original price was $234.95
49% marked down = $234.95 *49 / 100 = $115.13

So now the sale price = original price - price of 49% marked down

sale price = $234.95 - $115.13 = $119.82

Answer: sale price of a DVD player having a red tag marked down by 49% should be $119.82

Answer:

Emma ⇒ IQR = 3.5

Sally ⇒ IQR = 3

Olivia ⇒ IQR = 2.5

Emma - Sally - Olivia

Step-by-step explanation:

Emma's Scores:

<u>6 , 7 , 8 , 8 , </u><u>9 , 9</u><u> , 9 , 10 , 10 , </u><u>11</u> , <u>11</u><u> , 11 , 11 , 11 , </u><u>12 , 13</u><u> , 13 , 13 , 13 , 14</u>

LQ = (9 + 9) ÷ 2 = 9

UQ = (12 + 13) ÷ 2 = 12.5

IQR = 12.5 - 9 = 3.5

Sally's Scores:

<u>6 , 6 , 6 , 7 , </u><u>7 , 8</u><u> , 8 , 8 , 9 , </u><u>9</u> , <u>10</u><u> , 10 , 10 , 10 , 10</u><u> , 10 , 11</u><u> , 11 , 12 , 12 , 14</u>

LQ = (7 + 8) ÷ 2 = 7.5

UQ = (10 + 11) ÷ 2 = 10.5

IQR = 10.5 - 7.5 = 3

Olivia's Scores:

<u>6 , 6 , 7 , 7 , </u><u>7 , 8</u><u> , 8 , 8 , 8 , </u><u>9</u> , <u>9</u><u> , 9 , 9 , 9 , </u><u>10 , 10</u><u> , 12 , 12 , 13 , 14</u>

LQ = (7 + 8) ÷ 2 = 7.5

UQ = (10 + 10) ÷ 2 = 10

IQR = 10 - 7.5 = 2.5

Herky was given the following system of equations to solve. 3 x minus 2 y = 17. x minus 3 y = 1.
ioda

Answer:

(7, 2 )

Step-by-step explanation:

Given the 2 equations

3x - 2y = 17 → (1)

x - 3y = 1 → (2)

Rearrange (2) expressing x in terms of y by adding 3y to both sides

x = 1 + 3y → (3)

Substitute x = 1 + 3y in (1)

3(1 + 3y) - 2y = 17 ← distribute and simplify left side

3 + 9y - 2y = 17

3 + 7y = 17 ( subtract 3 from both sides )

7y = 14 ( divide both sides by 7 )

y = 2

Substitute y = 2 into (3) for corresponding value of x

x = 1 + 3(2) = 1 + 6 = 7

Solution is (7, 2 )
