Answer:

Step-by-step explanation:

Hello!

To compare different prices of several brands of a product the best is to express the price for the same quantities of product.

Since the three options are original in 300g, 450g and 600g, I'll express all prices on a base of 100g of product. You can use simple rule of three for this:

Option 1

300g cost $3.89

100g cost \frac{100*3.89}{300} = $1.296

Option 2

450g cost $ 4.77

100g cost \frac{100*4.77}{450}= $1.06

Option 3

600g cost $ 6.59

100g cost \frac{100*6.59}{600}= 1.098

So:

Option 1: $1.296/ 100g

Option 2: $1.06/100g

Option 3: $1.098/100g

The cheapest option is number 2

I hope this helps!

A bag contains 2 red, 5 blue, and 3 green marbles. A marble is chosen at random. What is the probability of NOT choosing a red m
Lapatulllka [165]

Step-by-step explanation:

  1. Number of red = 2
  2. Number of blue = 5
  3. Number of green = 3
  • total number of marbles = 10
<h3>probability of not choosing a red marble = 1--choosing a red marble.</h3>

<u>Because</u><u> </u><u>probability</u><u> </u><u>is</u><u> </u><u>always</u><u> </u><u>one</u><u>(</u><u>1</u><u>)</u><u>.</u>

<em>Probability</em><em> </em><em>=</em>

<em>1 -  \frac{2}{10}</em>

<em>\frac{8}{10}</em>

<em>\frac{4}{5}</em>

<em>Is</em><em> </em><em>the</em><em> </em><em>probability</em><em> </em><em>of</em><em> </em><em>not</em><em> </em><em>choosing</em><em> </em><em>a</em><em> </em><em>red</em><em> </em><em>marble</em><em>.</em>
