Answer:
the shop on the left is the cheaper of the two
Step-by-step explanation:
first shop ( on left )
£8.60 for 4 orchids , then for 12, that is 3 × cost of 4
12 orchids = 3 × £8.60 = £25.80
second shop ( on right )
[tex]\frac{1}{3}[/tex] of £5.40 = £5.40 ÷ 3 = £1.80
cost of one orchid = £5.40 - £1.80 = £3.60 , then
cost of 12 orchids = 12 × £3.60 = £43.20
Thus the cheaper price for 12 orchids is the first shop, the one on the left
