  12 250 mL containers

Step-by-step explanation:

Two of the 250 mL containers will have the same volume as a half-liter container (500 mL), but at a price that is $2.58 instead of $2.89.

Holly needs to buy 12 of the 250 mL containers of water to get the lowest price.

3 L = 3000 mL = 6(1/2 L) = 12(250 mL)

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
