Question

Mushrooms are healthy food for wild songbirds. Adam buys a 3.5 oz container of mealworms for $8.75. Marco buys a 3.75- oz container of mealworms for $9.75. ​Which container is a better buy?

Answer 1

Adam's container

Explanation:

Given

Adam

`Weight = 3.5\ oz`

`Amount = \$8.75`

Macro

`Weight = 3.75\ oz`

`Amount = \$9.75`

Required

Determine the better buy

First, we need to determine the unit cost per oz of each

i.e.

`Unit\ Cost = (Amount)/(Weight)`

For Adam:

`Unit\ Cost = (8.75)/(3.5)`

`Unit\ Cost = 2.5`

For Marco:

`Unit\ Cost = (9.75)/(3.75)`

`Unit\ Cost = 2.6`

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
