Question

A shop has an offer on jumpers as shown below. Buy 3 jumpers and get 1 free! Kara gets 5 jumpers. After applying the offer, each one ends up costing £4.20 per jumper. What is the regular cost of one jumper when not in this offer?

Answer 1

On buying 3 jumpers, we get 1 jumper free.

No of jumpers Kara got = 4

After applying the offer, cost of 1 jumper = £6.00

To Find:

The regular cost of one jumper when not in this offer.

Calculation:

- Total cost of jumpers = 4 × 6 = £ 24

- Kara got total 4 jumpers.

⇒ Kara bought 3 jumpers and got 1 jumper free as per the offer.

⇒ The cost of 3 jumpers = £ 24

⇒  The cost of 1 jumper = 24/3 = £ 8

- So, the regular cost of one jumper when not in this offer is £ 8.
