Plz ill mark you as brainles a company sells cereal in two different-sized boxes: a 17-ounce box for $2.89, and a 24-ounce box for $3.29. how do the unit prices of the two boxes compare? the smaller box is the better buy because it is approximately 1.4 cents cheaper per ounce. the smaller box is the better buy because it is approximately 3.3 cents cheaper per ounce. the larger box is the better buy because it is approximately 1.4 cents cheaper per ounce. the larger box is the better buy because it is approximately 3.3 cents cheaper per ounce.

So to compare boxes, you want to convert both to price per ounce unit.

So for smaller box, we have ratio $2.89 / 17 ounces which can be reduced to $0.17 per ounce. You just divide 2.89 by 17.

Now for larger box, we have ratio $3.29 / 24 ounces which can be reduced to approximately $0.14 per ounce. 0.137083333... to be exactly.

Larger box has smaller ratio compared to smaller box therefore larger box the is better buy.

The difference per ounce is 0.17 - 0.137083333... = 0.03291666... so that's 3.3 cents cheaper per ounce.

Final  The larger box is the better buy because it is approximately 3.3 cents cheaper per ounce.
