An analyst research is the relationship between different energy sources in each state for 2014. the data in the table shows the number of states that use coal in nuclear power as an energy source. given that a state does not use nuclear power, what percentage of those states use coal?

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints

2/3=10/15

1/5=3/15

10+3=13/15

2 13/15 is the answer
