What’s Goin’ On In Room 133

Some people…got to have it…some people…really need it.  Some people…uh, sorry – got a little carried away there.

But seriously, this simple interest stuff really is good stuff.  Remember the formula: I=prt.  As long as you’re multiplying in decimal form eveything is good.  You know, the deposit or loan say, $5,000.00 is already in decimal form, basically dollars and cents.  The interest rate, say, 7.5%, needs to be in decimal form.  That would be 0.075, right?  And the time needs to be in years.  If it’s for 2 years, you would just multiply by 2.  But if it is 3 months then you have to use the decimal equivalent in years.  Three months is one quarter of a year, right?  So instead of multiplying by 3 months, you would have to multiply by 0.25 years, right?  Works for me!  So in this little scenario, the interest on the deposit/loan works out to be $5,000 x 0.075 x 0.25 = $93.75.  Looking gooood!

Now git your groove on with page 359, numbers 3 – 7.  Manana!

Smokey would have loved it.  (Never mind; that was just for us old folks!) 

As for you guys, we are looking at page 130, dear colleagues, with questions 30 – 42 and Practice Quiz 2 as well.  Come with all the EVEN numbered questions done and be ready to discusss all with your colleagues.  (Dada da, dada da…)

We have reveiwed and massaged fractions almost to the point of no return.  So now, knock out questions #35, 43 and 50 on page 230.  Tomorrow we’ll review it and move on to addition, subtraction and mixed numbers.
