Answer:
The answer is Walmart.
Explanation:
Walmart sells 1.5 liters of lemonade for $0.75
K-Mart sells 2.72 liters of lemonade for $1.40
We must figure out how much it cost per 1 liter.
Walmart:
$0.75 / 1.5 Liters = $0.50
Walmart sells 1 liter of lemonade for $0.50
K-Mart:
$1.40 / 2.72 Liters = $0.51
K-Mart sells 1 liter of lemonade for $0.51
Clearly, their prices for 1 liter of lemonade are close, but Walmart sells 1 liter of lemonade for $0.01 cheaper than K-Mart.
