Answer 1

Option A -
`P=3.3w`

Explanation:

Given : A 12-ounce box of cereal costs $3.60.

To find : Which equation correctly relates the price (p) with the weight (w) of the cereal?

Solution :

The price be 'P' and weight be 'w'.

$3.60 is the price of box with weight 12-ounce

i.e.
`3.60P=12w`

Divide both side by 3.60.

`(3.60P)/(3.60)=(12w)/(3.60)`

`P=3.3w`

Therefore, Option A is correct.
