Answer:
Adam's container
Step-by-step explanation:
Given
Adam
[tex]Weight = 3.5\ oz[/tex]
[tex]Amount = \$8.75[/tex]
Macro
[tex]Weight = 3.75\ oz[/tex]
[tex]Amount = \$9.75[/tex]
Required
Determine the better buy
First, we need to determine the unit cost per oz of each
i.e.
[tex]Unit\ Cost = \frac{Amount}{Weight}[/tex]
For Adam:
[tex]Unit\ Cost = \frac{8.75}{3.5}[/tex]
[tex]Unit\ Cost = 2.5[/tex]
For Marco:
[tex]Unit\ Cost = \frac{9.75}{3.75}[/tex]
[tex]Unit\ Cost = 2.6[/tex]
The better buy of both is the one with the smaller unit cost.
Since 2.5 < 2.6, we can conclude that Adam's container is a better buy
