12 = 4x

12/4 = 4x/4

Given the following information, choose the brand that is the better buy. Brand A: $2. 16 for 18 ounces Brand B: $1. 50 for 12 o
topjm [15]

Using the division rule, the better buy is that Brand C gives 8.85 ounces for $1. Then the Brand C is better than Brand A, Brand B, and Brand D.

<h3>What is division?</h3>

The division means the separation of something into different parts, sharing of something among different people, places, etc.

Given

The brand that is the better buy.

1.  Brand A: $2.16 for 18 ounces

So in $1, the ounces will be

\rm Brand\ A = \dfrac{18}{2.16}\\\\Brand \ A = 8.33

Brand A gives 8.33 ounces for $1.

2.  Brand B: $1.50 for 12 ounces

So in $1, the ounces will be

\rm Brand\ B = \dfrac{12}{1.5}\\\\Brand \ B= 8

Brand B gives 8 ounces for $1.

3.  Brand C: $2.26 for 20ounces

So in $1, the ounces will be

\rm Brand\ C= \dfrac{20}{2.26}\\\\Brand \ C= 8.85

Brand C gives 8.85 ounces for $1.

4.  Brand D: $1.95 for 16 ounces

So in $1, the ounces will be

\rm Brand\ D= \dfrac{16}{1.95}\\\\Brand \ D= 8.21

Brand D gives 8.21 ounces for $1.

Thus, Brand C gives 8.85 ounces for $1.

Kitty [74]

Answer: 450 Minutes

Step-by step explanation:

135-x)/5 = hours connie runs

x/7 = hours Bonnie runs

(135-x)/5 + x/7 = 24

135-x + 5x/7 = 120

945-7x+5x = 840

-2x = -105

x = 52.5 miles = distance of Bonnie

52.5 miles / 7 m/hr = 7.5 hours = 450 minutes
