The survey is for a local newspaper that would like to know how effective its advertising strategy has been for a new publication. The cost for surveying is $11 for a low-income household, 58.5 for a mid income household, and 9.5 for a high-income household. The survey must indude at least 300 households. At least 25 must be high income homes and at least 145 should be low and mid-income households. The ratio of mid-income to low income household should not be greater that 3 to 1. Formulate a linear programming model that will minimize surveying costs How many decision variables are in this problem? 2 None of the amswers given here 03 05 00 04 QUESTION 27 How many constraints are there in this problem (do not indude the trivial constraints) None of the answers given here 04 01 05 02 03 QUESTION 28 How many of the constraints are sconstraints 00 1 5 03 6 or more Click Save and Submit to me and submit Click Save All Anto sou all annen QUESTION 29 Which of the following is the correct ratio constraint, given that X1 represents low income and X2 mid income?
