1. HOMEWORK ASSIGNMENT—
MRP PROBLEMS
Now try problems 1, 3, and 5 (parts a, c, and d) on pp in your textbook. Answers to these problems are on the slides that follow.
Note that problem 5 is very challenging, and will be done in detail in class.

2. Note: G is equivalent to G(1) and H is equivalent to H(1)
F(2) G H

J: 2 x 2 = 4
L: 1 x 2 = 2
A: 1 x 4 = 4
D: 2 x 4 = 8
J: 1 x 2 = 2
D: 1 x 2 = 2
Note: G is equivalent to G(1) and H is equivalent to H(1)
Simply increase the size of the screen to read this slide.
Totals: F = 2; G = 1; H = 1; J = 6; D = 10; L = 2; A = 4
