Add 2.38 and 4.89 then subtract 3 giving you 4.27
X = mia's score
eric scored 10 more then mia....so eric's score is x + 10
isabella scored 16 less then twice mia's score...so isabells's score is 2x - 16
so the expression x + x + 10 + 2x - 16 is a total of all 3 people's scores combined
Enjoy
200,000 + 80,000 + 3,000 + 900 + 80
