Answer:
The cost of 1 liter for the small can is £ 2.80, while the cost of 1 liter for the medium can is £ 2.64.
Step-by-step explanation:
Since cans of wood varnish come in three sizes, the 200 ml small can costs £ 0.56, the 500 ml medium can costs £ 1.32, and the 1 l large can costs £ 2.68, to determine the cost of 1 l for the small and medium cans the following calculation must be performed:
200 ml = 0.2 l
500 ml = 0.5 l
0.56 x 5 = 2.8
1.32 x 2 = 2.64
Thus the cost of 1 liter for the small can is £ 2.80, while the cost of 1 liter for the medium can is £ 2.64.
