At the grocery store, one brand of ice cream costs $4.50 for 48 ounces. The same brand costs $7 for 128 ounces or $3 for 64 ounces. Which size has the lower unit price

Answer 1

To find the unit price, we need to calculate the price per ounce for each package size.

For the 48-ounce size, the price per ounce is $4.50 / 48 = $0.0938 per ounce.

For the 128-ounce size, the price per ounce is $7 / 128 = $0.0547 per ounce.

For the 64-ounce size, the price per ounce is $3 / 64 = $0.0469 per ounce.

Based on these calculations, the size with the lower unit price is the 64-ounce size, which costs $0.0469 per ounce.
