Answer:
<em>~ Jill needs a minimum score of 90% to recieve an average of at least 92% on all her math quizzes ~</em>
Step-by-step explanation:
1. The table shows that her past weeks math quiz scores are: 92, 96, 94, 88
2. If she were to get a mean, or average, of at least 92, we could set up an equation to determine the minimum score she will recieve on her next quiz:
92 + 96 + 94 + 88 + x/ 5 = 92 ⇒ <em>(where x is the minimum score she should recieve on her next quiz to get an average of at least 92%)</em>
3. Now let us solve this equation for x through simple algebra ⇒
92 + 96 + 94 + 88 + x/ 5 = 92 ⇒
370 + x/5 = 92 ⇒
x/5 + 74 = 92 ⇒
x/5 = 18
x = 90

Answer:
720 copies must be sold to break even
Step-by-step explanation:
The break even point is the point where the revenue from sales equals the total cost.
The total cost can be expressed as;
Total cost=Initial costs+(cost per book×number of books made)
where;
Initial cost=$864
Cost per book=$0.80
Assume number of books made=n
replacing;
Total cost=(864)+(0.80×n)=$864+0.8 n
Total cost=0.8 n+864...equation 1
The total revenue from the book sale can be expressed as;
Total revenue=Price per book×number of books sold
where;
Price per book=$2
number of books sold=n
replacing;
Total revenue=(2×n)=2 n...equation 2
Equate equation 1 to equation 2
0.8 n+864=2 n
2 n-0.8 n=864
1.2 n=864
n=864/1.2
n=720
720 copies must be sold to break even
4.876 < 4.879
the first three digits are the same, however the last digit, which is the fourth digit from both sides are 6 and 9
6 is less than 9 therefore that determines the whole value of 4.876 to be less than 4.879
