Given:
A 6 ounce bottle of dressing costs $1.56 a 14 ounce bottle costs $3.36 a 20 ounce bottle costs $5.60
Determine which has the lowest cost per ounce.
Solution:
In order to do so, we just need to solve for the unit rate of each bottle by dividing the total cost by the ounces.
= $1.56/6 ounces
= $0.26 per ounce
= $3.36/12 ounces
= $0.168 per ounce
= $5.60/20 ounces
= $0.28 per ounce
Final answer:
The lowest cost per ounce is a 14-ounce bottle that costs $3.36.
