14 Orlando wants to borrow $3,000 for the
purchase of a used car. He has to pay
back the loan after 4 years. The two loan
options are simple interest at a rate of
5.8% each year, or interest compounded
annually at a rate of 5.2% each year,
Which loan option should he choose,
simple or compound, and how much less
will he owe for that option? (Lesson 11)
F Compound interest; $0.22
G Simple interest; $0.63
H Compound interest; $21.62
3 Simple interest; $62.92

Suppose we have a set of small wooden blocks showing the 26 letters of the english alphabet, one letter per block. (think of scrabble tiles.) our set includes 10 copies of each letter. we place them into a bag and draw out one block at a time. (a) if we line up the letters on a rack as we draw them, how different ways coukl we fill a rack of 5 letters? (b) now suppose we just toss our chosen blocks into a pile, and whenever we draw a letter we already have, we put it back in the bag and draw again. how many different piles of 5 blocks could result? possible? piles will contain at least one repeated letter? (c) if we draw out 5 blocks wit hout looking at them, how many different piles are (d) if we draw out 5 blocks without looking at them, how many of the possible 2. (4) consider the following formula. 12 give two different proofs, one using the factorial formulas and the other combina torial.
