Marked price = Rs 650 and Discount percentage = 2.5%. find selling price

levacccp [35]

Answer:

The selling price is <u>Rs.633.75</u>.

<h3><u>Solution</u> :</h3>

Here we have given that :

$\pink\star$ Marked Price = Rs.650
$\pink\star$ Discount % = 2.5 %

We need to find the selling price.

Firstly, finding the discount by substituting the values in the formula :

${\longrightarrow{\sf{Discount = Marked \: Price \times Discount \%}}}$

${\longrightarrow{\sf{Discount =650\times 2.5\%}}}$

${\longrightarrow{\sf{Discount =650\times \dfrac{2.5}{100}}}}$

${\longrightarrow{\sf{Discount = \dfrac{650 \times 2.5}{100}}}}$

${\longrightarrow{\sf{Discount = \dfrac{1625}{100}}}}$

${\longrightarrow{\sf{Discount = 16.25}}}$

Hence, the discount is Rs.16.25.

$\rule{200}2$

Now, finding the selling price by substituting the values in the formula :

${\longrightarrow{\sf{Selling \: Price = Marked \: Price - Discount}}}$

${\longrightarrow{\sf{Selling \: Price = 650 - 16.25}}}$

${\longrightarrow{\sf{Selling \: Price =633.75}}}$

Hence, the selling price is Rs.633.75.

$\rule{300}{2.5}$

Put the following equation of a one into a slope -intercept form, simplifying all fractions.

dusya [7]

Answer:

y = -4/3x -9

Step-by-step explanation:

Slope intercept form is

y = mx+b where m is the slope and b is the y intercept

8x+6y = -54

Subtract 8x from each side

8x+6y-8x = -8x-54

6y = -8x-54

Divide each side by 6

6y/6 = -8x/6 -54/6

y = -4/3x -9
