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.
$9.75 because one taco is 0.75 and 13 x 0.75 is $9.75
Answer:
1/2
Step-by-step explanation:
x∧(3/2) = 64 = 8²
(3/2)Log₈ x = 2 Log₈ 8
Log₈ x = 4/3
x = 8∧(4/3)
Therefore
4* x∧(-3/4) = 4* 8∧(-1) = 4/8 = 1/2 = 0.5
