Since 4 nights cost $356, 356÷4=89, so one night costs $89. 7-4=3, so 89×3 is 267. 267+356 is 623. The total cost for 7 nights would be $623
        
                    
             
        
        
        
remember that local minimuns are points in which the function was decreasing and starts increasing. 
you can try two ways of doing it, graphing the functions or using derivatives.
since this are twelve functios the easier way is to graph them. 
start by function y=x
in this case this function is continously increasing as x increases, which means that it does not have any local maxima or minima.
now do the same for 

this graph has a local minima on th 
 
        
                    
             
        
        
        
72/96 * 100= 75% so the answer is 75%
