Answer 1

To determine which size has the lower unit price, we need to calculate the price per ounce for each size.

For the 48-ounce size:
Price per ounce = $4.50 / 48 ounces = $0.09375 per ounce

For the 128-ounce size:
Price per ounce = $7 / 128 ounces = $0.0546875 per ounce

For the 64-ounce size:
Price per ounce = $3 / 64 ounces = $0.046875 per ounce

Comparing the prices per ounce, we can see that the 64-ounce size has the lowest unit price.

Answer 2

To determine which size has the lower unit price, we need to compare the price per ounce for each size.

For the 48-ounce size, the cost is $4.50. To find the price per ounce, we divide the cost by the number of ounces: $4.50 / 48 = $0.0937 per ounce.

For the 128-ounce size, the cost is $7. To find the price per ounce, we divide the cost by the number of ounces: $7 / 128 = $0.0547 per ounce.

For the 64-ounce size, the cost is $3. To find the price per ounce, we divide the cost by the number of ounces: $3 / 64 = $0.0469 per ounce.

Comparing the price per ounce for each size, we find that the 64-ounce size has the lowest unit price at $0.0469 per ounce.
