$6.40 because 32 ounces is the difference 128 and 96 hence 32 is 1/3 of 96 so divide $4.80 by 3 which is $1.60 then add $1.60 + $4.80 =$6.40
we know that
A 96 -ounce container of orange juice cost $4.80
so
by proportion
Find the cost of a 128 -ounce container
96 4.80 o u n ces $ = 128 x o u n ces $ 96 ∗ x = 128 ∗ 4.80 x = 128 ∗ 4.80/96 x = $6.40
Verify the unit rates
96 4.80 o u n ces $ = 0.05 o u n ce $
128 6.40 o u n ces $ = 0.05 o u n ce $
therefore
the answer is
$6.40
A 128-ounce container should be sold for $6.40 to maintain the same unit rate of $0.05 per ounce as a 96-ounce container costing $4.80. This ensures both containers provide the same cost per ounce. Confirming this by calculating the unit rate of the 128-ounce container also results in $0.05 per ounce.
