Question

Jason went shopping.

Answer 1

The price of the watch before the discount is £33.4

Step-by-step explanation:

• Jason bought a watch and a pair of trainers for a total price of £53.55
• The total price he bought has a 15% loyalty discount.

Let us assume,

The original price of the watch and a pair of trainers before the discount = x

• The price 53.55 is less than 15% of x.
• We know that the original price x is 100%
• Therefore, the price 53.55 is 75% of x.

⇒ $53.55=(75/100)\times x$

⇒ $53.55 = 0.75\times x$

⇒ $x = 53.55 / 0.75$

⇒ $x = 71.4$

The original price of a watch and a pair of trainers before the discount is £71.4

It is given that,

Before the discount, the trainer's were priced at £38

Before the discount, the total cost = trainer's cost + price of the watch.

⇒ 71.4 = 38 + price of the watch

⇒ Price of the watch = 71.4 - 38 = 33.4

∴ The price of the watch before the discount is £33.4
