If a discount of 15/2%is allowed on a book that costs 800naira what Will be the sale price

To determine the sale price, we need to multiply the original price of the book by the discount (15/2%) and subtract from the original price.

15/2% is equivalent to 15/2 / 100 = 0.15 * (1/2) / 100 = 0.0015

Sale price = 800 - (800 * 0.0015)
Sale price = 800 - 1.20
Sale price = 798.80 naira

Therefore, the sale price of the book with a discount of 15/2% (0.0015) is 798.80 naira.

To find the sale price after a discount of 15/2% on a book that costs 800 naira, follow these steps:

1. Calculate the discount amount:
Discount amount = (15/2)% of the original price
Discount amount = (15/2/100) * 800

2. Subtract the discount amount from the original price:
Sale price = Original price - Discount amount
Sale price = 800 - (15/2/100) * 800

Let's calculate it:

Discount amount = (15/2/100) * 800
Discount amount = (15/2) / (100/1) * 800
Discount amount = 15 * 4 * 800 / 2 / 100
Discount amount = 15 * 4 * 8
Discount amount = 480

Sale price = 800 - 480
Sale price = 320 naira

Therefore, the sale price after a discount of 15/2% on a book that costs 800 naira will be 320 naira.
