How can I show original and sale prices in my cart?

Im looking for some help please

On my site, when you buy a sale item (add it to your cart) and then view cart, it shows the price

However I want it to show the original price (scored out) and the new price

As currently I think its quite deceptive to customers , who want to see the saving / sale

Ive attached images

Can anyone help?

@spoiledbratuk - this will need code editing, if you are not familiar with coding then you will need to get someone
