To determine which size has the lower unit price, we need to calculate the cost per ounce for each size. The unit price is found by dividing the total cost by the number of ounces.
Let's calculate the unit prices for each size:
For 48 ounces:
Cost = $4.50
Unit Price = Cost / Ounces = $4.50 / 48 ounces ≈ $0.094 per ounce
For 64 ounces:
Cost = $3
Unit Price = Cost / Ounces = $3 / 64 ounces ≈ $0.047 per ounce
For 128 ounces:
Cost = $7
Unit Price = Cost / Ounces = $7 / 128 ounces ≈ $0.054 per ounce
Comparing the unit prices, we can see that the 64-ounce size has the lower unit price, which is approximately $0.047 per ounce. The 48-ounce size has a unit price of approximately $0.094 per ounce, and the 128-ounce size has a unit price of approximately $0.054 per ounce.
Therefore, the size with the lower unit price is the 64-ounce size.
To determine which size has the lower unit price, we need to calculate the unit price for each size and compare them.
For the 48-ounce container, the unit price can be calculated by dividing the cost ($4.50) by the number of ounces (48).
Unit price for 48 ounces = $4.50 / 48 ounces = $0.09375 per ounce
For the 128-ounce container, the unit price can be calculated by dividing the cost ($7) by the number of ounces (128).
Unit price for 128 ounces = $7 / 128 ounces = $0.0546875 per ounce
For the 64-ounce container, the unit price can be calculated by dividing the cost ($3) by the number of ounces (64).
Unit price for 64 ounces = $3 / 64 ounces = $0.046875 per ounce
Comparing the unit prices, we can see that the 64-ounce container has the lowest unit price at $0.046875 per ounce.
