Katen [24]

Answer:

3012 books

Step-by-step explanation:

Let y = number of books produced and sold

Total cost = Fixed cost + Variable cost = 32379 + 10.75*y

Total sales = 21.50*y

Set these equal to each other and solve for y

21.50*y = 32379 + 10.75*y

10.75*y = 32379

B = 3012

The publisher must produce and sell 3012 books.

Next-door neighbors Bob and Jim use hoses from both houses to fill Bob's swimming pool. They know that it takes 12 h using both

Leokris [45]

Answer:

Jim's hose: 27 hours.

Bob's hose: 21.6 hours.

Step-by-step explanation:

Let t represent hours taken by Jim's hose.

Part of pool filled by Jim's hose in 1 hour would be $\frac{1}{t}$ .

We have been given that Bob's hose, used alone, takes 20% less time than Jim's hose alone. This means that Bob's hose take will take 80% time of Jim's hose that is $0.8t$ .
