Kristopher has a coupon for $10 off any item at his favorite electronics shop. If he plans to use the coupon to purchase and item that costs $80, by what percentage will the price be decreased before tax?

Answers

Answer:

12.5%

Step-by-step explanation:

Kristopher has a coupon for $10 off any item at his favorite electronics shop. If he plans to use the coupon to purchase and item that costs $80, by what percentage will the price be decreased before tax?

The formula for Percentage Decrease =

Decrease in price/ Initial price × 100

Decrease in price = $10

Initial price = $80

Hence:

$10/$80 × 100

= 12.5%

Hence, the percentage the price will be decreased by before tax is 12.5%

The bike store marks up the wholesale cost of all of the bikes they sell by 30%. Andre wants to buy a bike that has a retail price of $125. We need to find the wholesale (original) price of this bike. What percent of the wholesale (original) price is the retail price?

Answers

Answer:

Wholesale Price = $96.15Retail price percentage = 130%

Step-by-step explanation:

Wholesale price was marked up by 30% and became $125.

Assume wholesale price is x. Expression will be;

125 = x + (30% * x)

125 = 1.3x

x = 125/1.3

x = $96.15

Retail price percentage = 125/96.15

= 1.30

= 130%

Sindhu’s present age is thrice of Shilpa. If Shilpa’s age three years ago was x, then Sindhu’s present age is
3 (x – 3)
3x + 3
3x – 9
3(x + 3)

Answers

Answer:

I think "D"- 3(x + 3)

Step-by-step explanation:

as  3 years ago - x

so present age of shilpa  - x +3

~~~~~~~~~~~~~

present age  of sindhu - 3 (x+3)

i guess : )

Shilpa's age three years ago

Shilpa's age now = x + 3

Sindhu's age now = 3(x + 3)

a rectangle is 6 times as long as it is wide. the perimeter is 140 cm. find the area of the rectangle. round to the nearest tenth if necessary.

Answers

Answer: [tex]w = 10[/tex]

Step-by-step explanation:

Our perimeter will be 140 cm and our width of the rectangle will be 6w. We will then divide 14w and 140 by 14 so we can get w by itself. Then, we will divide the perimeter by the width.

Step 1: Let 6w will be our length and let the perimeter be 140 cm.

[tex]6w, P = 140 cm[/tex]

Step 2: Perimeter means that you add up all the 4 sides of the rectangle.

[tex]P = 140 = w + w + 6w + 6w = 14w[/tex]

[tex]P = 140, 14w[/tex]

Step 3: Divide both sides 14 to get the single w variable.

[tex]\frac{140}{14} = \frac{14w}{14}[/tex]

Step 4: Simplify.

[tex]10 = w[/tex]

Step 5: Flip sides.

[tex]w = 10[/tex]

What is the value of g(-9) for the function g(x) = x2 - x?

Answers

Answer:
