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

Blank A : Fran's food

Blank B : Diane's Deli

Blank C : Fran's food

Step-by-step 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 $16\frac{2}{3}$ or $\frac{50}{3}$ ounces cereal = $3.36

∴ The price of 1 ounce cereal = $\frac{3.36}{\frac{50}{3}}$

= $\frac{3.36\times 3}{50}$

= $0.2016

Price of cereal at Diane's Deli :

∵ The price of $24\frac{3}{5}$ or $\frac{123}{5}$ ounces of cereal = $5.52

∴ the price of 1 ounce of cereal = $\frac{5.52}{\frac{123}{5}}$

= $\frac{5.52\times 5}{123}$

= $0.2244

For cereal Fran's food is better buy

Price of Apple sauce at Fran's food :

∵ the price of $10\frac{1}{5}$ or $\frac{51}{5}$ ounces apple sauce = $3.80

∴ the price of 1 ounce apple sauce = $\frac{3.80}{\frac{51}{5} }$

= $\frac{3.80\times 5}{51}$

= $0.3725

Price of apple sauce at Diane's Deli :

∵ the price of $4\frac{2}{7}$ or $\frac{30}{7}$ ounces apple sauce = $0.86

∴ the price of 1 ounce apple sauce = $\frac{0.86}{\frac{30}{7} }$

= $\frac{0.86\times 7}{30}$

= $0.2006

For apple sauce Diane's Deli is better buy

Price of soup at Fran's food :

∵ the price of $16\frac{1}{2}$ or $\frac{33}{2}$ ounces soup = $1.99

∴ the price of 1 ounce soup = $\frac{1.99}{\frac{33}{2} }$

= $\frac{1.99\times 2}{33}$

= $0.1206

Price of soup at Diane's Deli :

∵ the price of $24\frac{3}{4}$ or $\frac{99}{4}$ ounces soup = $3.99

∴ the price of 1 ounce soup = $\frac{3.99}{\frac{99}{4} }$

= $\frac{3.99\times 4}{99}$

= $0.1612

For soup Fran's food is better buy

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know logb c = loga c/loga b

we want to convert to base 10 so a = 10

by default, we do not write the 10 c = 4 and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
