Acook uses fifteen 2- litre bottles of cooking oil in 4 weeks. If he decides to buy 5 litre tins of oil instead , how many tins of cooking oil will be use over a 10 weeks period if the rate at which he uses it remains unchanged?

i think it is 15 tins

Step-by-step explanation:

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
