Question

Cierra is buying juice. She needs 5 liters. A half liter juice cost $2.86. A 250​-milliliter container of juice costs ​$1.05. What should Cierra buy so she gets 5 liters at the lowest price?

Answer 1

Answer: 250 mL Juice container

Explanation:

Given

Half liter juice costs $2.86 i.e.

`(1)/(2)\ L\rightarrow\$2.86\\\\1\ L\rightarrow(2.86)/((1)/(2))=\$5.72\\\\5\ L\rightarrow\$28.6`

A 250 mL juice costs $1.05 i.e.

`250\ mL=0.25\ L\rightarrow \$1.05\\\\1\ L\rightarrow (1.05)/(0.25)=\$4.2\\\\\Rightarrow 5\ L\rightarrow \$21`

The cost of 250 mL Juice packet is low for 5 L quantity, therefore, Cierra must buy 250 mL Juice container
