Question

HELP ASAP!!!!!!
A figure skater needs a total score of at least 90 to move on to the next round. Her total score is the average of four judges’ scores. The first three judges’ scores were 83, 88, and 92. The figure skater found out she made it to the next round.

What is the minimum score the fourth judge could have given her?

Answer 1

To get the answer to this question is,
(83 + 88 + 92 + x) / 4 > = 90
(263 + x) / 4 > = 90....Multiply both of sides by 4, then eliminating the 4 on the left.
263 + x > = 90 * 4
263 + x > = 360
x > = 360 - 263
x > = 97
So, the minimum score would be '97' for your answer.
