Answer:
it's C
Step-by-step explanation:
<span>(a) $7.04
(b) 704/1599
(c) 0.44
(d) 14
(e) $98.56
(a) How much profit does Lucy earn when she sells a necklace?
Since the problem states that her profit is the sale price minus the cost of materials and labor, we have the following equation.
P = $15.99 - $3.38 - $5.57
P = $12.61 - $5.57
P = $7.04
So her profit is $7.04 per necklace.
(b) Write a fraction of the profit per sale price of the necklace. Record your answer as a fraction using whole numbers.
The raw fraction is 7.04/15.99, to get rid of the decimal point, multiply top and bottom by 100, getting 704/1599.
The prime factors of 704 are 2,2,2,2,2,2,11 and the prime factors of 1599 are 3,13,41. Since neither 704, nor 1599 share any common factors, the fraction can't be reduced and the final answer is 704/1599.
(c) What decimal of every dollar of the sale price of the necklace is profit using the fraction from Part (b)?
Pardon the lack of formatting
704/1599 = 0.4403
Rounded to the nearest hundredth gives 0.44
(d) Lucy collected $223.86 selling necklaces at a craft fair. How many necklaces did Lucy sell? Show your work.
This question is asking for total cost. So divide the $223.86 by the sale price of $15.99.
$223.86 / $15.99 = 14
14 necklaces were sold.
(e) How much profit did she earn from the number of necklaces she sold? Show your work.
Since we know from (a) that she has $7.04 profit per necklace, just multiply the amount of profit by the number sold. So
$7.04 * 14 = $98.56</span>
Answer:
c
Step-by-step explanation:
negative and positive make a negative so it cant be 16 it has to be -16
First setting up the first step of the equation
3/8*16=?
Does 16/1=16? Yes it does! So you can put 16/1 in place of the 16!
So, 3/8*16/1= 48/8
And 48/8=6
<span>The solution is 6! Do you have further questions?</span>

15. Interpret
I'll try to explain this quick so you can sleep. Sleep is very important for brain activity and is very important to help us learn more efficiently and to help us feel more energized and healthy (and sleep is just amazing in general) :)
All of the numbers below 1000 are going to give us negative number answers. For all of them, we just subtract 1000 from it to see how much over or below we are.
February: 10
March: -5
April: 50
May: -25
June: -20

16. Analyze
An <u>integer </u>is just a number with no fraction or semi-value that is part of it. So 7 and -10 are integers while -1.5 and 2/3 are not.
A negative integer is one below zero, and a positive is one above zero.
PART A: Letters a and c represent the negative integers because they are to the left of zero on the number line.
PART B: letters b and d represent the positive integers because they are above zero on the number line.
PART C: They can be described as additive inverses, which have a different sign but the same <u>absolute value</u> (distance from zero). They are called this because when you combine them you get zero.

Enjoy your sleep and keep on learning! :D
