hi i'm new so everyone add me pls!

Recently, two of the top three college textbook publishers announced plans to get into the textbook rental business. On its face this seems like a good deal for college students, but the real question is whether this heralds a beginning of cheaper textbook prices or is just another pricing stunt from an industry famous for stunting.

For years, the college textbook publisher business model has been consistent. Most of the revenues the publisher gets for a new edition comes in the first semester. Over the remaining life of that edition, competition and used books chew up an increasing amount of the market share and reduce the publisher revenues to a trickle. This is why publishers charge high prices for the books so they can be sure to recoup their expenses. From a student’s perspective, the average cost of that textbook is similar — almost all copies that first semester cost full retail price, with cheaper used books making up more of the volume in subsequent semesters. Used book dealers make their money after the first semester assuming they bet correctly on the books still being in demand. (Meaning, they buy back books they think will be in need again, and decline to buy back books that won't be used and longer.)

(See how the money gets divided in the secret behind textbook costs.)

In a textbook rental scenario, things change for everyone:

• Publishers get less money that first semester (reflecting the 40-70% of retail price floated by Cengage), but continue to get similar revenue levels in subsequent semesters because there are few if any used books. Their revenue curve, which before was extremely front-loaded, is now more level. In fact, the ongoing revenue potential could in some cases extend the hyper-accelerated revision cycle leaving the same edition in play for longer (further raising the profitability of that edition.) Sounds like a win for the publisher.
• Students get to spend less that first semester for their textbook, but in subsequent semesters can end up paying more since there are no more cheap used books. (This is especially true in cases where the student wants to keep the textbook, since in the absence of used books they are forced to purchase at full price.) Sounds like a loss for the student unless they’re in that first semester.
• Used book dealers really get screwed on this one, since their supply and market both dry up entirely. A resounding LOSS for them.

For years the used book market has been kicking the publishers' asses, revenue-wise. For a while they had some success with bundling the textbook with workbooks or CDs/DVDs, knowing that bookstores wouldn’t buy those back and forcing them to replenish their stocks from the publisher (at full price). Now, with rentals, it appears that they’ve hit on another tactic that could solve their problem.

How about the college student’s problem of higher textbook costs, though? It doesn’t seem like their expenses are getting a reduction… #FAIL

 

Hi,

 I have this problem that I am not able to solve because I do not know anything about mixtures.

  A car's radiotor contains 12 L of antifreeze at 25% concentration. How many liters must be drained and then replaced by pure antifreeze to bring the concentration to 50%?

 The answer is 4L but the book did not provide workings. Please show me the workings.

Thank you.

Can someone explain in detail the following formula?

(Gradient)*E=0 (without source or current)

Let the real money demand in the economy equal LD = 10 + 2Y – 8r. The price level P is fixed at P = 1. Y is the level of output and r is the rate of interest. What is the LM curve for this economy?

If you aren't into college yet and have time to plan ahead, here is some good information on the whole FAFSA process and how to minimize your EFC.

Thanks to your votes for nominations and first round of voting, College-Cram is a finalist for this year's awards in the "How To" category. Mashable recognizes social networking websites in various categories in its annual awards competition. College-Cram is nominated as "How-To" since Mashable doesn't feature a "social learning" category (yet). In fact, College-Cram.com is the only social learning site in the Open Web Awards competition this year, and it will take the help of students on campuses around the world to put them over the top in the final round of voting.

Social learning is a mashup of social networking and educational resources. Many websites offer tools or frameworks that help students organize themselves, but a true social learning site also has actual academic help for students trying to pass their courses. College-Cram is a true social learning site. Rudy Lopes, (VP of Operations) said “Maybe if we win, next year they will add a social learning category. That would be a good thing.”

Congress: Hold on here folks. You don't even have a plan. Think this through and get back to us.

Auto Industry: You were right. We need 34 Billion dollars right away, or we are going out of business.

Congress: That's more like it. Now, don't spend it all in one place. See you later.
