Find the sales price for a $900 TV with a 25% discount.
Discount = Regular Price X Rate of Discount Sales Price= Regular Price - Discount.
b. Discount (mark down Expression) = ((Original price – (Original price x discount rate))

Answers

Answer:

$675

Step-by-step explanation:

100%=>$900

25%=>X

25% × $900 ÷ 100% = $225

So $900 - $225 = $675

AWNSER

$ 675 with discount

EXPLANATION

If it is 25% off of the sales price we can infer that you are paying 75% of the sales cost.

To find the price you answer the equation

900•.75= 675

Therefore the total cost with the discount of 675 dollars.

Three times Mary’s age added to Beth’s age is 34 years. Half of Mary’s age minus Beth’s age is 1 year. How old are Mary and Beth?

Answers

The answer for this is 10 4

The age of Mary and the age of Beth will be 10 years and 4 years, respectively.

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

Three times Mary’s age added to Beth’s age is 34 years. Half of Mary’s age minus Beth’s age is 1 year.

Let 'x' be the age of Mary and 'y' be the age of Beth. Then the equations are given below.

3x + y = 34        ...1

x/2 - y = 1          ...2

From equations 1 and 2, then we have

3(2y + 2) + y = 34

6y + 6 + y = 34

7y = 34 - 6

7y = 28

y = 4

Then the value of the variable 'x' is given as,

3x + 4 = 34

3x = 30

x = 10

The age of Mary and the age of Beth will be 10 years and 4 years, respectively.

More about the solution of the equation link is given below.

The sum of two numbers is 14 and their difference is 18. Find the larger number.

Answers

Answer:

Let a = the larger number and b = the smaller

a + b = 14

a - b = 18

We can add the 2 equations together.

2a = 32

2a/2 = 32/2

a = 16

The answer is 16
Because a = the larger number and b = the smaller number so equations would look like a+b=14 and a-b=18 we can add the 2 equations together and get 2a=32 then simply to 2a/2=32/2 then simplify that and get the answer a=16
