Question

6. A Book was put into the sale and is now £12, how much was it originally if the sale was 20% off?​

Answer 1

Answer:

£15

Step-by-step explanation:

Firstly, we need to note the equation representing the original value by "x" that would give £12.

$\implies \: x \times 0.8 = 12$

Where,

• x is the original value
• 0.8 also known as 80% of the original value goften by 100% - sales percent off = 100% - 20%
• 12 is the value gotten from the 20% cutoff of the original value

Solution:

$\sf \implies x \: \times 0.8 = 12$

$\sf \implies 0.8x = 12$

$\sf \implies x = \frac{12}{0.8}$

$\sf \implies x = 15$

Therefore, the original price of the book before the 20% off is £15
