What is Unitary Method?
'In unitary method we will learn how to find the value of a unit from the value of a multiple and the value of a multiple from the value of a unit.'
According to the given problem,
The larger box costs [tex]\frac{4.59}{20}[/tex] = $0.2295 = 22.95 cents/ounce
The smaller box costs [tex]\frac{2.52}{12}[/tex] = $0.21 = 21 cents/ounce
now, 22.95 > 21
Therefore, the cereal in the smaller box costs less per ounce.
Hence, we can conclude that the larger box costs 23 cents/ounce approximately, the smaller box costs 21 cents/ounce and the smaller box costs less per ounce.
