Answer:
The answer is below
Step-by-step explanation:
At Lidal shop, 4 toilet rolls is sold for £2.40. Therefore the cost of each toilet roll is given as:
Cost of each roll at Lidal = £2.40 / 4 = £0.60 per roll
Cost of 36 rolls = cost for each roll * 36 rolls = £0.60 per roll * 36 rolls = £21.6
At Oldi shop, 9 toilet rolls is sold for £4.68. Therefore the cost of each toilet roll is given as:
Cost of each roll at Oldi = £4.68 / 9 = £0.52 per roll
Cost of 36 rolls = cost for each roll * 36 rolls = £0.52 per roll * 36 rolls = £18.72
