At the grocery store one brand of ice cream cost $4.50 for 48 ounces the same brand cost seven dollars for 128 ounces or three dollars for 64 ounces which size has the lower unit price
To find the unit price, we need to divide the cost by the number of ounces.
For the first option, the unit price is $4.50 / 48 ounces = $0.09375 per ounce.
For the second option, the unit price is $7 / 128 ounces ≈ $0.05469 per ounce.
For the third option, the unit price is $3 / 64 ounces = $0.04688 per ounce.
Therefore, the third option, which costs three dollars for 64 ounces, has the lower unit price.
