Answer:
64.8 in
Step-by-step explanation:
The pipe is 324 in and you cut in in two. Since we know that one piece is five times the length of the other, we can make the equation 324=5x. Divide both sides by five gets us 64.8 = x.
To check our work, let's multiply 64.8 by 5. It does equal 324 so we are correct.
Answer:
3,604 books
Step-by-step explanation:
We have 2 situations: situation A and situation B. What we are looking for is the number of books that has situation A equal to situation B. So the game plan is to write the equations for A and B, set them equal to each other, and then solve for the unknown number of books, x.
Situation A: If each book costs 19.25 to produce and the number of books is x, we express that as 19.25x. The fixed cost to use that company, regardless of the number of books it produces for you, is 22,427. Which means it is going to charge you 22,427 whether you produce 1000000 books or no books at all. The equation for A is:
C(A) = 19.25x + 22,427
Situation B uses the exact same reasoning, with the cost of each book being 10.50x and the flat rate cost of 53,962. Therefore, the equation for B:
C(B) = 10.50x + 53,962
We need the number of books where A = B, so we set the equations equal to each other and solve for x:
19.25x + 22,427 = 10.50x + 53,962 so
8.75x = 31,535 and
x = 3604
