Blank B : Diane's Deli

Blank C : Fran's food

Explanation:

Nina shops at two different stores Fran's Foods and Diane's Deli.

comparison of prices of items on both stores :

Price of cereal at Fran's food :

∵ The price of
`16(2)/(3)` or
`(50)/(3)` ounces cereal = $3.36

∴ The price of 1 ounce cereal =
`(3.36)/((50)/(3))`

=
`(3.36* 3)/(50)`

= $0.2016

Price of cereal at Diane's Deli :

∵ The price of
`24(3)/(5)` or
`(123)/(5)` ounces of cereal = $5.52

∴ the price of 1 ounce of cereal =
`(5.52)/((123)/(5))`

=
`(5.52* 5)/(123)`

= $0.2244

For cereal Fran's food is better buy

Price of Apple sauce at Fran's food :

∵ the price of
`10(1)/(5)` or
`(51)/(5)` ounces apple sauce = $3.80

∴ the price of 1 ounce apple sauce =
`(3.80)/((51)/(5) )`

=
`(3.80* 5)/(51)`

= $0.3725

Price of apple sauce at Diane's Deli :

∵ the price of
`4(2)/(7)` or
`(30)/(7)` ounces apple sauce = $0.86

∴ the price of 1 ounce apple sauce =
`(0.86)/((30)/(7) )`

=
`(0.86* 7)/(30)`

= $0.2006

For apple sauce Diane's Deli is better buy

Price of soup at Fran's food :

∵ the price of
`16(1)/(2)` or
`(33)/(2)` ounces soup = $1.99

∴ the price of 1 ounce soup =
`(1.99)/((33)/(2) )`

=
`(1.99* 2)/(33)`

= $0.1206

Price of soup at Diane's Deli :

∵ the price of
`24(3)/(4)` or
`(99)/(4)` ounces soup = $3.99

∴ the price of 1 ounce soup =
`(3.99)/((99)/(4) )`

=
`(3.99* 4)/(99)`

= $0.1612

For soup Fran's food is better buy

Answer 2

Blank A: The better buy is Fran's

Blank B: The better buy is Diane's

Blank C: The better buy is Fran's

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
