Part A - Calculate the following expressions given the following variables to two decimal places:

a=2

b = 4.7

c=3

d = 4.2

1. answer1=b+a/cd

2. answer2=(a+b)/cd

3. answer3=d*-bfloat(c/a)

4. answer4=ab*(c%int(d))

5. answer5=d/a+(b*c)

Part B Show the contents of each set of variables after each statement below. Take the previous statements into account (i.e. changes from earlier statements are applied) and list all three variables at each step:

 a = 40 b = 20 c = 50 

1.a = b

2.c = a

3.b = c

 d = 25 e = 35 f = 15 

4.d = f

5.f = e

6.e = d
