One brand of ice cream cost $4.50 for 48 oz. The same brand cost $7 for 128 oz or $3 for 64 oz. Which size has the lower unit price?
To determine the unit price, we need to divide the cost by the number of ounces.
For the first option:
Unit price = $4.50 / 48 oz = $0.09375/oz
For the second option:
Unit price = $7 / 128 oz = $0.0546875/oz
For the third option:
Unit price = $3 / 64 oz = $0.046875/oz
From the calculations, we see that the third option has the lowest unit price at $0.046875/oz.
