Question

Find each unit price and decide which is the better buy. Assume that we are comparing different sizes of the same brand.Crackers:$1.19 for 12 ounces$1.59 for 16 ouncesAfter finding this information out decide which is a better buy

Answer 1

To find the unit price, we need to divide the price by the amount of ounces:

$1.19 for 12 ounces:

$\frac{1.19}{12}=\frac{119}{1200}\approx0.099166$

$1.59 for 16 ounces:

$\frac{1.59}{16}=\frac{159}{1600}=0.099375$

We can see that in the 4º decimal place, the first option has a 1 and the second option has a 3. Thus, is better to buy the second option

To 3 decimal places:

First option: $0.099 per ounce

Second option: $0.099 per ounce
