Answer:
The publisher must sell 4,632 books in order to break even(total sold equals production costs).
Step-by-step explanation:
So the bookstores are really making $24-10.25 in profit off of each book. This equals $13.75 profit for every book sold.
So you set up an equation:
13.75x=$63,690
x=63690/13.75
x=4632
B. is the answer if you look closely
Answer:
15
Step-by-step explanation:
Replace x with -3
f(x) = -4(-3) +3
= 15
Answer:
5 sessions
Step-by-step explanation:
2 1/2 = 5/2
No. of sessions = 5/2 x 2/1 = 5
Let the integers be x + (x+1) + (x + 2)
<span>x + (x+1) + (x + 2) = 267 </span>
<span>3x + 3 = 267 </span>
<span>3x = 264 </span>
<span>x = 88 </span>
<span>88+89+90=267 </span>
<span>Largest integer=90 </span>
<span>Another method </span>
<span>267/3 = 89 </span>
<span>It's the average,so it has to be the middle one. </span>
<span>Thus 89, then I took 89 - 1 = 88 and 89 + 1 = 90 and just put them in order. </span>
<span>88+89+90=267 </span>
<span>Largest integer=90</span>
