Linda owns 4 shares of a certain stock. Yesterday the total value of her shares went down by 32 dollars. What was the change in
Annette [7]

Answer:

The value of each share decreased by $8.

Step-by-step explanation:

Number of shares of a certain stock Linda owned = 4

Total value of shares went down by = $32

So find the change in value of each share.

Solution:

Let the total value of each share in dollars be = x

Value of 4 shares in dollars will be = 4x

The total value of shares went down by $32

So, new value of 4 shares = 4x-32

New value of each share = \frac{New\ value\ of\ total\ shares}{4}

⇒ \frac{4x-32}{4}

Splitting the denominators.

⇒ \frac{4x{{4}-\frac{32}}{4}

⇒ x-8

Original value of each share in dollars was = x

New value of each share in dollars = x-8

Thus, we can see that the value of each share decreased by $8.

Octavia buys a pair of jeans for $20.50 plus 8% tax.
dezoksy [38]

Answer:

$56.70 all together

Step-by-step explanation:

$22.14 for the jeans

$34.56 for the jacket

$56.7 all together

Take your tax and move the decimal over to the left by 2 spaces

8. becomes .08

take .08 and multiply it by the price so

20.50 x .08= 1.64

and

32 x .08=2.56

the number you get is how much the tax is, $1.64 is 8% of $20.15

take that number and add it to your price

$1.64+$20.50= $22.14
