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:-

$\\ \sf\longmapsto \dfrac{2.56}{32}=0.08$

#Size X

• 48 fluid ounces=4.80$

1 fluid ounce

$\\ \sf\longmapsto \dfrac{4.80}{48}=0.1$

We can see

0.08<0.1

• So Size X is better to buy
