Answer:
Cereal Box A is better
Step-by-step explanation:
Given
Two cereal boxes; A and B
Cereal A costs $4.20
Cereal A weighs 14 ounce
Cereal B costs $3.90
Cereal A weighs 12 ounce
To get which is better, we need to calculate the cost of each cereal per unit ounce
To do this, we divide cost of cereal by weight of the box.
i.e. Unit Price = Cost of box ÷ Weight of box
For Box A
Unit Price = $4.20 ÷ 14 ounces
Unit Price = $0.3 per unit ounce
For Box B
Unit Price = $3.90 ÷ 12 ounces
Unit Price = $0.325 per unit ounce
By being better, means cheaper.
Since Cereal Box A costs less than Cereal Box B, then Box A is better
