Here we need to find how much costs to buy 6 cans in each shop and compare the prices. We will find that the correct option is:
Right Price is cheaper by 44 pence.
Smart Buy:
Each can costs 60p, and there is a 10% off.
Then the price of each can is:
P = 60p*(1 - 10%/100%) = 60p*(1 - 0.1) = 60p*0.9 = 54p
Then the cost of 6 cans will be:
p1 = 6*54p = 324p
Right Price:
Here each can costs 70p.
But there is a promotion of 3 for 2.
So if you buy 2 cans (for 2*70p = 140p) you get 3 cans.
This means that here you get 3 cans for 140p.
Then 6 cans, which is the double of 3, costs 2*140p = 280p
(where we assume that you can use the promotion two times)
Then we can see that the Right Price is cheaper.
To find the difference, we just need to subtract the smaller price to the largest price:
324p - 280p = 44p
We can conclude that the Right Price is cheaper by 44 pence.

We are required to find the shop where's the price of 6 cans of coke is cheaper.
Right Price is cheaper by 44 pence
Smart buy:
One can costs 60p
Special offer: 10% off
Cost of each can after deducting special offer = 60p - (10% of 60p)
= 60p - (0.1 × 60p)
= 60p - (6p)
= 54p
cost of 6 cans = 54p × 6
= 324p
Right price:
One can costs = 70p
Special offer: 3 for 2
Cost of 2 cans = cost of one can × 2
= 70p × 2
= 140p
3 for 2 means you'll get 3 cans and pay for 2
In other words, 3 cans cost 140p
Cost of 6 cans = cost of 3 cans × 2
= 140p × 2
= 280p
Difference in cost of 6 cans = Smart buy - Right price
= 324p - 280p
= 44p
