<h1 class="center">Unit Price</h1>
|
|
|

|
<p style="float:left; margin: 0 10px 5px 0;"><img src="images/bottle-2l.svg" alt="2 Liters for $3.80" width="100"></p>
|
|
<p>The "Unit Price" (or "unit cost") tells us the cost per liter, per kilogram, per pound, etc, of what we want to buy.</p>
|
|
<p>Just divide the cost by the quantity:</p>
|
|
|
|
<div class="example">
|
|
<p>Example: 2 liters for $3.80 is $3.80/2 liters = <b>$1.90 per liter</b></p>
|
|
|
|
</div>
|
|
|
|
<h2>Comparing</h2>
|
|
|
|
<p>Comparing Unit Prices can be a good way of finding which is the "best buy".</p>
|
|
|
|
<div class="example">
|
|
<p>Example: What is best</p>
|
|
<ul>
|
|
<li>2 liters of Milk at $3.80, or</li>
|
|
<li>1.5 liters of Milk at $2.70 ?</li>
|
|
</ul>
|
|
<p>In this case the "Unit" is 1 liter, and the Unit Prices are:</p>
|
|
<ul>
|
|
<li>$3.80 / 2 liters = $1.90 per liter</li>
|
|
<li>$2.70 / 1.5 liters = $1.80 per liter</li>
|
|
</ul>
|
|
<p>So the lowest Unit Price (and the best bargain) is 1.5 liters at $2.70.</p>
|
|
</div>
|
|
<p>But it does not tell us the <b>quality</b> of what we are buying, but it can help us make a decision.</p>
|
|
<h2>Per Item</h2>
|
|
<p>If something is sold in number of items (for example "10 pencils") then the same method can be used:</p>
|
|
|
|
<div class="example">
|
|
|
|
|
|
<h3>Example: What is best</h3>
|
|
<p style="float:right; margin: 0 0 5px 10px; transform: scale(2);">
|
|
<img src="../images/style/pencil.svg" alt="Pencil">
|
|
</p>
|
|
<ul>
|
|
<li>10 pencils for $4.00, or</li>
|
|
<li>6 pencils for $2.70 ?</li>
|
|
</ul>
|
|
<p>Here is the Unit Cost:</p>
|
|
<ul>
|
|
<li>$4.00 / 10 = $0.40 per pencil</li>
|
|
<li>$2.70 / 6 = $0.45 per pencil</li>
|
|
</ul>
|
|
<p>So the lowest Unit Price (and the best bargain) is 10 pencils for $4.00</p>
|
|
</div>
|
|
