Answer:
The 40 oz cat food costing $8.00 is the lowest cost.
Step-by-step explanation:
Here, to compare the price of the cat food we need to find the UNIT RATE of the cat food of each size bag.
24 oz bag cost $5.49.
⇒ Cost of 1 oz cat food = [tex]\frac{5.49}{24 } =0.22875[/tex]
or, the cost of 1 oz of cat food here is $0.22875.
40 oz bag cost $8.00.
⇒ Cost of 1 oz cat food = [tex]\frac{8}{40 } =0.20[/tex]
or, the cost of 1 oz of cat food here is $0.20.
64 oz bag cost $15.99.
⇒ Cost of 1 oz cat food = [tex]\frac{15.99}{64 } =0.2498[/tex]
or, the cost of 1 oz of cat food here is $0.2498.
Now, comparing the cost of 1 oz of cat food we seen that the lowest price of cat food per oz is $0.20 in the 40 oz pack.
Hence, the 40 oz cat food costing $8.00 costs the least.
