2. LECTURE 19 Review Lecture 18 MS EXCEL Financial Functions
Perform a break-even analysis.

3. EXCEL FUNCTIONS FINANCIAL ANALYSIS
SLN 
  Returns the straight-line depreciation of an asset for one period
SYD
   Returns the sum-of-years' digits depreciation of an asset for a specified period

6. EXCEL FUNCTIONS FINANCIAL ANALYSIS
VDB
   Returns the depreciation of an asset for a specified or partial period using a declining balance method
XIRR
   Returns the internal rate of return for a schedule of cash flows that is not necessarily periodic

10. LINEAR EQUATIONS Solve two linear equations with two variables
Solve problems that require setting up linear equations with two variables
Perform linear Cost-Volume-Profit and break-even analysis employing:
The contribution margin approach
The algebraic approach of solving the cost and revenue functions

11. SOLVING LINEAR EQUATIONS
2x – 3y = – 6
x + y = 2
Solve for y
2x – 3y = – 6
2x + 2y = 4
-5y = -10
Y = 2

12. SOLVING LINEAR EQUATIONS
2x – 3y = – 6
x + y = 2
Solve for x
Substitute y = 2
2x – 3(2) = – 6
2x =
2x = 0
x = 0

13. SOLVING LINEAR EQUATIONS
2x – 3y = – 6
x + y = 2
Solve for x
Substitute y = 2
2x – 3(2) = – 6
2x =
2x = 0
x = 0

14. Solving Two Equations with Two Unknowns
check your answer by substituting the values into each of the equations
Equation 1: 2x – 3y = -6
x = 0 y = 2
LHS = 2x – 3y = 2(0)-3(2)
= -6 = RHS
Equation 2 : x + y = 2
LHS = = x + y = 0 +2 = 2 = RHS
