During a football/soccer match, a goalkeepers save rate was 33 1/3%. .After saving the next shot, it rose to 40%. How many more consecutive shots on target must be saved to raise the save rate to 60%?

from  3 out of 9    to    4 out of 10        to   9 out of 15       five more in a row    

 

x = saves    y = attempts

 

.33333y = x     and     .4(y+1) = x+1    which is   x = .4y-.6    sub this into the forst equation

 .33333y = .4y-.6

results in y = 9      so   x = 6        add 1 attempt and 1 save to get    4 out of 10      

    then    add 5 more to get 9 out of 15 = 60 %
