REVIEW OF THE BASICS:

Managerial Economicsapplies relevant micro and macro economic theory using different analytical tools (including statistical tools, basic algebraic and graphing tools, computer software like EXCEL,...), to business problems, whilst developing general principles that can be applied to the business decision-making process.

These exercises are therefore intended to help prepare you review some of those basic algebraic tools that might have been forgotten. Please do not be intimated. You will find them easier than you think. The same is true of the basic economics principles.

Please answer all questions. Answers are to be posted in the DROP BOX at the end of Week 2. (That means, you have two weeks to complete them).

1) Solve: x + 79 = 194 x = 115

2) Solve: x - 56 = 604 x = 660

3) Solve: 6x = 36 x = 6

4) Solve: x / 5 = 10 x = 50

5) Solve the Problem: 6/1÷ 2/3 = 9

6) Problem: 3/4 * 6/7 = 0.642

7) Graph: y = 2x + 1 (use values of X= 0,1,2,-1)

(0,1)
(1,3)
(2,5)
(-1,-1)

8) Simplify: (-5)^3 = 125

9) Simplify: -33 - (-3)2 + (-2)2 = -31

10) Opportunity cost is best defined as:

A) The amount given up when choosing one activity over the next best alternative.

B) The opportunity to earn a profit that is greater than the one currently being made.

C) The amount that is given up when choosing an activity that is not as good as the next best alternative.
