Natalija [7]

Answer:

Blank A: The better buy is Fran's

Blank B: The better buy is Diane's

Blank C: The better buy is Fran's

Step-by-step explanation:

* Lets explain how to solve the problem

- The better buy is the cheapest price

# Blank A

∵ The Fran's foods price is $3.36 for 16 2/3 ounces

∴ The price of each ounce = 3.36 ÷ 16 2/3 = $0.2016

∵ The Diane's Deli price is $5.52 for 24 3/5 ounces

∴ The price of each ounce = 5.52 ÷ 24 3/5 = $0.2244

∵ The price per ounce in Fran’s Foods store less than Diane’s Deli

∴ The better buy is Fran's

# Blank B

∵ The Fran's foods price is $3.80 for 10 1/5 ounces

∴ The price of each ounce = 3.80 ÷ 10 1/5 = $0.3725

∵ The Diane's Deli price is $0.86 for 4 2/7 ounces

∴ The price of each ounce = 0.86 ÷ 4 2/7 = $0.2007

∵ The price per ounce in Diane’s Deli store less than Fran’s Foods

∴ The better buy is Diane's

# Blank C

∵ The Fran's foods price is $1.99 for 16 1/2 ounces

∴ The price of each ounce = 1.99 ÷ 16 1/2 = $0.1206

∵ The Diane's Deli price is $3.99 for 4 2/7 ounces

∴ The price of each ounce = 3.99 ÷ 24 3/4 = $0.1612

∴  The price per ounce in Fran’s Foods store less than Diane’s Deli

∴ The better buy is Fran's
