Please solve this question withvfull process i will wark as braineast a) After allowing 5 % discount on the marked price of a ra

schepotkina [342]

Answer:

Let the marked price be x

Discount % = 10%

Discount = 10\% \times x = 0.1x10%×x=0.1x

Cost after discount = x-0.1x = 0.9x

10%vat is charged on it

Cost including VAT = 0.9x+0.1(0.9x)=0.99x0.9x+0.1(0.9x)=0.99x

We are given that it's price became rs 1672

So, 0.99x = 1672

x=\frac{1672}{0.99}x=0.991672

x=1688.88

Discount = 0.1x=0.1(1688.88)=168.888

Hence The discount

liubo4ka [24]

Answer:

The rate of change of Paolo Portraits is $15 per photo and the rate of change of clear image studio is $12 per photo. Paolo Portraits charges are higher than the clear image studio.

Step-by-step explanation:

The rate of change represent the change in one variable with respect to another variable. It also known as slope.

It is given that Paolo Portraits charges $15 per photo with no sitting fee. It means the rate of change of Paolo Portraits is $15 per photo.

The function for Paolo Portraits charges is defined as

$f(x)=15x$

From the given graph it is noticed that the line is passing through the points (0,0) and (1,12).

The slope of the line is

$m=\frac{y_2-y_1}{x_2-x_1}=\frac{12-0}{1-0}=\frac{12}{1}=12$

The function for clear image studio is

$g(x)=12x$

It means the rate of change of clear image studio is $12 per photo.

The rate of change of Paolo Portraits is more than rate of change of clear image studio.

Therefore Paolo Portraits charges are higher than the clear image studio.

What is the value of x in the equation 3 minus 2 x = negative 1.5 x? –6 –2 2 6

olga_2 [115]

Answer:

x=118.25

Step-by-step explanation:

3−2x=−1.5−6−226

3+−2x=−1.5+−6+−226

−2x+3=(−1.5+−6+−226)(Combine Like Terms)

−2x+3=−233.5

Step 2: Subtract 3 from both sides.

−2x+3−3=−233.5−3

−2x=−236.5

Step 3: Divide both sides by -2.

−2x

−2

−236.5

−2

x=118.25
