Questions

Here are some of the questions we get all the time. Don’t see your question? No problem, just send us an email.

Our system is very transparent. You don’t need a credit card to get started and signing up is completely free. Once you have an account, you will unlock our free concept questions and gain access to select dynamic calculators. This way you can try us out and see if we’re a good fit for you, completely risk-free.

Our more advanced math-based calculators do require credits to unlock, similar to an arcade: you can purchase credits and then use your credits as needed to unlock our premium calculators. You are in full control of how many credits to purchase and use, and there are no recurring fees or hidden charges. We are a no-nonsense business, period.

CourseStar is simple: we provide you with check figures, not lengthy boring explanations. Our software provides you with check-answers using your actual numbers: just place your inputs into the blue boxes and the check figure solutions instantly appear in the green output areas against which you can then compare your own individual work. We respect our users’ privacy and we do not share user information with universities.

The best way to answer that is to take us for a spin. First, sign up for free and save your textbook(s) to your favorites list. Then after clicking on your book, simply search for your homework problems within your book using the search bar. Then simply unlock the calculator and input your numbers.

Problem 5.07 – Montezuma Tees sells custom screen printed t-shirts at a price of $25.60 each. The variable cost per shirt is $3.25. Fixed operating costs including rent amount to $42,500 per year.

Required:

  1. Determine the breakeven quantity
  2. Calculate the breakeven sales revenue

Nope, we don’t operate that way! CourseStar works like an arcade: you only pay for what you use, and a lot of our content is free. There is no monthly fee and there are no hidden charges. What you see is what you get.

Our system is much more equitable than paying month after month for a service you don’t use all the time. We are NOT yet another subscription you forget to cancel! Simply add credits to your account when you need them, and use them up as you go. Simple.

CourseStar is fair. Not all calculators are created equal, some required a lot more time and effort to create by our staff, and thus the cost of those calculators reflects that. For this reason, very lengthy problems, or questions that require more advanced mathematics behind the scenes use more credits than the easier problems. Extremely difficult problems will be marked HARD.
