A figure skater needs a total score of at least 90 to move on to the next round. The total score is the average of four judges' scores. The first three judges' scores were 83, 88, and 92. The figure skater made it to the next round. What is the minimum score the fourth judge could have given?

90x4=360
83+88+92=263
360-263=97

therefore the minimum score required is 97

hope this helps :)
