"Anyone who cannot cope with mathematics is not fully human. At best he is a tolerable subhuman who has learned to wear shoes, bathe, and not make messes in the house."
- Robert A. Heinlein, Time Enough for Love

Just had to get that one out of the way due to the subject.

Note that Heinlein also said in the same book,
"A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects."

His point is that you need SOME math skills in life -- well, you can forget about balancing accounts if you want to run for Congress but you'll darn well want to know how to do that if you're going to run the family business and keep it going.

The real question is, what kind of math do you need to pass to get your degree and function in your family business and what's holding you up in that? As with anything else, a lot depends on the instructor -- I can certainly understand the frustration if you have someone just tossing you a textbook and expecting you to pick it up via osmosis. You probably just need someone who can show you the techniques and relevance (like Schoolhouse Rock did with basic multiplication, history and science for kids 30-40 years ago).

Basic algebra is definitely applicable to running a business. How many units of items A, B and C do you need? Would it be more efficient to get them in pallets of size X or Y? Even basic trig is very useful in daily life. On the other hand, you probably don't need an introduction to calculus for a history degree (although it might be helpful when trying to understand radiocarbon dating).

So ...

1. Determine your goal. If running the family business rather than shuttering it is important to you then do what you need to do to make that happen.

2. Figure out what you need to make that happen. Specifically which math classes do you need to get your degree? Can you place out of any of them based on real world practical experience?

3. What is preventing you from making that happen? Instruction in the relevance of various topics? Time or the right practice problem sets?

4. Find out specific options to assist with the specific remaining problems. A tutor MAY help but figuring out what you want from the tutor will greatly increase the chances of success.
