As usual, I’m posting when I should be in bed.
Last week they started digging lots of holes around the house in preparation for jacking up the foundation, which has settled.
Last Sunday, Dad had something resembling a heart attack. He still has to go back to the cardiologist for some tests.
Apparently he had a heart attack in 1997 that no one saw fit to tell me about. Apparently of all my siblings, I was the only one who wasn’t told. Again.
This week, they started digging holes INSIDE the house for jacking up the foundation. Watching someone take a jackhammer to the middle of your living room is a surreal experience, let me tell you.
I had a mid-term in Advanced Food Prep and Macro Economics last week. Got a C in Food Prep, and a high C / low B in Macro Econ.
This week, midterm in Basic Food Prep (I think I got about a C) and Intro. to Economics. I think I got about a B there, to. I need to discuss one of the questions with the instructor when he gets back from his conference. None of the multiple choices made sense for the question, but one of them DID make sense if he made a typo in the question. So I gave that answer. And I’m 100% sure none of the choices could have been correct, and 100% sure the answer I gave would be correct if made the typo I think he did.
(Your company has a TFC of $10,000 to produce an item, wth an AVC of $30/unit. You can sell the product for $50/unit. How many units would you have to sell to break even?)
TFC + (AVC * Units made) == Price * Units sold
$10,000 + ($30 * x) = $50 * x.
$10,000 + ($30 * 500 units) = $25,000 = $50 * 500 units.
But the choices were
- 3334
- 3335
- 5000
- 5001
However: $100,000 + ($30 * 5,000) = $250,000 = $50 * 5,000.
So if he typod and and meant TFC of $100,000, answer c works. None of the given choices works with a TFC of $10,000.
This is also exactly the kind of problem we learned to solve in the first week of Intermediate Algebra. Even if I couldn’t do it algebraicly, I had my trusty TI-86 with me (we were allowed a calculator during the exam), and I just needed to punch in the two equations and see where their graphs intersect. Or with numbers like these, use the table function. Trying to find a window setting that will show the intersection of the graphs is a pain.
Which is just a long winded way of saying knowledge learned in the two classes overlaps.
It’s also another way of saying: I’m actually learning in Intermediate Algebra. Not just learning but passing. And not just passing, either. I’m aceing the class. Which is saying something since I failed it at least twice, and possibly 3 times already. (I can’t actually remember how many times I failed the class now.) But an extra 10 years, a different college, different teacher, a calculator that practicly does the work for you (which is required for the class), and an approach to teaching the subject matter that actually helps you understand what it is the calculator is doing will do that I guess. I used to say I loved math until I got to algebra. I hated algebra. I just didn’t grok algebra. I loved geometry. The numbers in geometry meant something to me. Not algebra.
I get algebra now. If I get at least a B in this class (in the bag) I’ll continue on and study more math. And I’ll try to get into sections taught by this teacher, to. She treats us like a bunch of high school students (it’s clear she taught high school for many years), and she constantly makes simple errors on the overhead, but she’s good at communicating the material.
Ok, I’ve rambled enough. Bed time. I have to go to church in the morning.
