Question

A store sells two sizes of bottled water. Size A is 32 fluid ounces (f1 oz) for $2.56 and Size X is $4.80 for

48 fluid ounces. Which is the better buy? Justify your answer.

Answer 1

#size A

• 32fluid ounces=$2.56

1 fluid ounce:-

`\\ \sf\longmapsto (2.56)/(32)=0.08`

#Size X

• 48 fluid ounces=4.80$

1 fluid ounce

`\\ \sf\longmapsto (4.80)/(48)=0.1`

We can see

0.08<0.1

• So Size X is better to buy
