Excel's Solver has been used in the spreadsheet below to solve a linear programming problem with a maximization objective function. The two tables below show the input section and the sensitivity analysis, respectively. Direction: For numerical answers, round non $-$ integer values to $2$decimal places. Keep integer values as integers. What is the optimal value for $1?$Answer: $1=$What is the optimal value for $2?$Answer: $2=$Would you pay $ $1.30$each for up to $50$more units of resource $2?$Answer: Enter Y'es or No $.$Is the current solution still optimal even when the objective function coefficient of product $2$is decreased to $2?$Answer: $$Enter Y'es or No $.$Does the second constraint have a slack or a surplus? What is its current value? Answers: $$If $30$units of resource $1$were available, would the profit increase by $ $5.4?$
