Jenny wants to buy some blackberries. Three stores sell blackberries at different prices:

store a. store b.

$2.40/lb $1.28/8 oz

store c.

$1.08/6 oz

Which store has the best deal? Give your reasons.

Store A.

There are 16 ounces in a pound. 16 ounces for $2.40

2.40/16=0.15

Store B.

$1.28/8 = 0.16

0.16*16 = $2.56

Store C.

$1.08/6 = 0.18

0.18*16 = $2.88

So the answer is STORE A. Broken down by ounce, store A is the cheapest per ounce.
