Question

In a sale, the price of a sofa is reduced by 70%. The sale price is £255. Find the price before the sale.

Answer 1

Step-by-step explanation:

₹364.2857 is the rate of sofa before sale

Answer 2

Answer:

the price before the sale is 850

Step-by-step explanation:

First remember the unknown authentic rate as 'x'. Then remember the fee of cut price. To discover the real cut price, multiply the bargain fee through the authentic amount 'x'. To discover the sale rate, subtract the real cut price from the authentic amount 'x' and equate this to given sale rate.

Step 1: Convert the percentage cut price to a decimal through dividing through 100% . Step 2: Set up the equation P=(1−d)x P = ( 1 − d ) x to discover the authentic rate of the object in which P is the sale rate, d is the bargain as a decimal, and x is the authentic rate of the object.

Solution

Price x .30 (100%-70%)=income rate

rate x .30 = 255

rate = 255/.30

rate = 850

the rate earlier than the sale is 850
