A furniture store advertises a 40% off liquidation sale on all items. What would the sale price be, p, on a $2530 dining room set? Write an equation.

In mathematics, an equation is a statement that asserts the equality of two expressions. The word equation and its cognates in other languages may have subtly different meanings; for example, in French an equation is defined as containing one or more variables, while in English any equality is an equation.

An equation has operators and an = sign

There is a difference between an expression and an equation

Given

Price = 2530

Final Sale Price = 40% of 2530 or % of Price

Final Price = Price - % off

Final Price = ( 2530 ) - ( 40/100 × 2530 )

Final Price = 2530 - 1012

Final Price = $1,518.00

Remember the formula for finding the discount price of an item. Where S = sale price, r = discount percentage rate and p = original price, the discount formula is: S = p - rp.

Let us substitute



S = P - rP

S = 2530 - (40/100 ) ( 2530 )

S = 2530 - 1012

S = 1518

S = $1518

S = P - rP

is one equation

Answer 2

If there is no saale that means you have to pay full price which is 100%

There is 40% sale

So you only need to pay 60% (100% - 40%)

The normal Price of furniture that you want to buy is $2530

So you only have to pay 60% of$2530

P = 60% * $2530

= 60/100 * $2530

= $1518
