How much will you save if you buy an item listed at $75.50 at a 25% discount?

Answers

Answer:

Amount of money saved = $18.87

Step-by-step explanation:

List Price of the item which is bought = $75.50

Now, This item is on discount.

Discount rate offered by the seller on the item = 25%

Discounted Price of the Item = List Price - 25% of List price

⇒ Discounted Price = 75.50 - 25% of 75.50

⇒ Discounted Price = 75.50 - 0.25 × 75.50

⇒ Discounted Price = 75.50 - 18.875

⇒ Discounted Price = $56.63

Now, Amount of money saved = List price - Discounted price

⇒ Amount saved = 75.50 - 56.63

Hence, Amount of money saved = $18.87

From the information we have been given, the original sale price is 75.50 and the discount is 25% of this price.

We need to calculate what value 25% stands for, so:

25 % of 75.50 → (25/100) ×100 → 0.25 ×75.50 = 18. 88

Therefore value of 25% of original price is 18.88 dollars

Rounded off 18.88 = 18.90 dollars.

You will save $ 18.90

The item will be sold to you at:

75.50 - 18.90 = 56. 60 dollars.

Step-by-step explanation:

The focus of the comparison in question 1413 is not provided in the question itself. To determine the focus, you would need additional context or information about the content or subject being discussed. Both options (A and B) suggest a comparison between molecules involved in different cycles (nitrogen cycle or carbon cycle), but without more information, it's not possible to specify which one is the correct focus.

Y=8 when x=20 find y when x= 30

Answers

Answer:

y=13

Step-by-step explanation:

if x=20 when y=8 (we can creat equation )

x=2y+4 (you can prove that the equation is correct by substitute )

so the question is if x=30 find the value of y

30=2y+4

30‒4=2y

26=2y

26/2=2y/2

13=y

Calculate ten minus four point three five

Answers

the answer is five point six five, 5.65

Final answer:

To calculate ten minus four point three five, you subtract 4.35 from 10. The result of this calculation is 5.65.

Explanation:

To calculate ten minus four point three five, you simply subtract 4.35 from 10. This is a basic math operation, and can be solved on a calculator or by hand. If you are performing the operation by hand, you align the numbers vertically by their decimal points and subtract normally, remembering to carry over any values from the right of the decimal point:

10.00
- 4.35
----------
5.65

So, ten minus four point three five equals 5.65.

three bags of potatoes and four cases of corn cost $40. Five bags of potatoes and two cases of corn cost $34. Find the cost of one bag of potatoes and the cost of one case of corn.

Answers

Use variables and set up equations.

$3p + 4c = 40 \n 5p + 2c = 34$

Next, get one variable with equal coefficients.

$3p + 4c = 40 \n 10p + 4c = 68\ (multiplied\ both\ sides\ by\ 2)$

Then get it alone on one side.

$4c = 40-3p \n 4c = 48-10p$

Now we can use substitution. Since $40-3p = 4c$ , substitute $40-3p$ for $4c$ in the other equation and you'll get an equation with just one variable to simplify and solve.

$40-3p = 68-10p \n 40+7p = 68 \n 7p = 28 \n \boxed{p = 4}$

We can then use $p = 4$ in an earlier equation to find $c$ .

$5p + 2c = 34 \n 5*4 + 2c = 34 \n 20 + 2c = 34 \n 2c = 14 \n \boxed{c=7}$

3p + 4c = 40 ⇒ 15p + 20c = 200
5p + 2c = 34 ⇒ 15p +   6c = 102
      14c = 98
   14    14
      c = 7
          5p + 2(7) = 34
      5p + 14 = 34
      - 14 - 14
      5p = 20
   5 5
      p = 4
      (p, c) = (4, 7)
