PLS HELP ASAP A shop has an offer on jumpers as shown below.

Buy 4 jumpers and get 1 free!

Kara gets 6 jumpers.
After applying the offer, each one ends up costing £4.50 per jumper.
What is the regular cost of one jumper when not in this offer?

The regular cost of one jumper not in this offer is 4.50$

Kara gets 6 jumpers and since if she buys 4 she gets 1 free that means Kara only needs to spend money on 5 total jumpers. It costs 4.50$ per each jumper with the offer, and with the offer u buy 5, but without the offer you buy 6. to find the the total amount of cost for the jumpers you do 6(4.50) bc without the offer you buy 6 and each jumper costs 4.50 and from that u get 27. 27 is the total cost of all 6 jumpers. to find the cost of an individual jumper you do 27 divided by 6 which is 4.5. meaning without the offer a jumper costs4.50$

The solution is: 6(4.50) divided by 6
