Help ASAP Holly is buying water. She needs 3 liters. A half-liter of water costs $2.89. A 250-milliliter container of water costs $1.29. What should Holly buy so she gets 3 liters at the lowest price? Explain.

9514 1404 393

  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)

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
