Decide whether the statement makes sense. Explain your reasoning.If you have $5, then you will buy a hot dog; and, contrapositively, if you don't have $5, then you won't buy a hot dog. (Hint: focus on whether the word "contrapositively" is used correctly.)
What will be an ideal response?
Does not make sense. The contrapositive of "If p, then q" is "If not q, then not p." The contrapositive of "If you have $5, then you will buy a hot dog" is "If you will not buy a hot dog, then you don't have $5." What is actually given is the inverse. (Explanations will vary.)

Solve the problem.A computer manufacturer has three outlet stores that sell its four computer systems. The following table shows the numbers of systems sold by the three stores in July.
The prices of the systems are: $1200 for System 1, $1500 for System 2, $1600 for System 3, and $1700 for System 4. Write the information from the table as a 4 x 3 matrix B. Write a row matrix A for which the entries represent the prices for the systems. If 
find c12. What does this entry of C represent?
A. c12 = 151,000. c12 represents the total sales at Store 1 in July. B. c12 = 173,000. c12 represents the total sales at Store 2 in July. C. c12 = 161,000. c12 represents the total sales at Store 3 in July. D. c12 = 141,000. c12 represents the sales of System 2 at all stores in July.
