A garage that sells cars offers a 15% discount when paying cash.
pav-90 [236]

The non cash price of the car before discount is £8000.

What is discount?

  The discount is determined by dividing the purchase price by the item's par value. Discount is a type of cost price reduction or deduction for a product. It is primarily employed in consumer interactions when discounts on various goods are offered to customers. A percentage represents the discount rate.

Here Discount rate = 15%

Car price after discount = £6800

Here we know that before discount car price is 100%.

Then, after discount car price will be (100%-15%)=85%

Here , 85%= 6800

Then, 100%=x

=> x = \frac{6800*100}{85}

=> x = £8000.

The non cash price of the car is £8000.
