7) Staples charges $28 for 8 boxes of pencils and $47 for 4 pencil sharpeners. Ms. Felix orders 70 boxes of pencils and 21 penci
barxatty [35]

Answer:

<u><em>Ms. Felix would spend $491.75 on her order.</em></u>

Step-by-step explanation:

First, let's identify the components of this word problem that we'll need to solve it. We know that Staples charges $28 for 8 boxes of pencils, and $47 for 4 pencil sharpeners. Before we do anything else, we'll find the unit price of  the pencils and pencil sharpeners to make it easier for us. Let's begin with the boxes of pencils. 28 ÷ 8 = $3.50 per box of pencils. As for the pencil sharpeners, 47 ÷ 4 = $11.75 per sharpener. Now that we know the basic costs, let's use them to solve our problem at hand. We'll multiply the number of items ordered by the base cost of the item.

Boxes Of Pencils:

70 × $3.50= $245.00

Sharpeners:

21 × $11.75= $246.75

Now that we know the cost of the two seperate items Ms. Felix ordered, let's add them to get our final answer.

<h3>$245 + $246.75 = $491.75</h3><h3 />

Our final answer would be $491.75.

16 feet 10 minutes. 40 feet write as proportion
WINSTONCH [101]
The answer is 16/10 = 40/25
You divided 16 by 40 to see what you need to multiply 16 to get 40. When I did that I got 2.5. So I did that to the 10 and got 25 minutes. Hope this makes sense
