The 128 ounce size has the lower unit price.
To determine which size has the lower unit price, we need to calculate the unit price for each size.
For the 48-ounce size:
Unit price = $4.50 / 48 ounces = $0.09375 per ounce
For the 128-ounce size:
Unit price = $7 / 128 ounces = $0.0546875 per ounce
For the 64-ounce size:
Unit price = $3 / 64 ounces = $0.046875 per ounce
Comparing the unit prices, we can see that the 64-ounce size has the lower unit price.
To find the lower unit price, we need to calculate the price per ounce for each size of the ice cream.
For the first option, the ice cream costs $4.50 for 48 ounces. To find the price per ounce, we divide the total cost ($4.50) by the number of ounces (48).
$4.50 ÷ 48 ounces = $0.09375 per ounce
For the second option, the ice cream costs $7 for 128 ounces. To find the price per ounce, we divide the total cost ($7) by the number of ounces (128).
$7 ÷ 128 ounces = $0.0546875 per ounce
For the third option, the ice cream costs $3 for 64 ounces. To find the price per ounce, we divide the total cost ($3) by the number of ounces (64).
$3 ÷ 64 ounces = $0.046875 per ounce
Comparing the unit prices, we can see that the third option (64 ounces for $3) has the lowest unit price at $0.046875 per ounce. Therefore, the 64-ounce size has the lower unit price.
