player	score
elise	$9 \times 10^3$
mari	200,000
ryan	$8 \times 10^4$
tiana	$4 \times 10^5$

Explanation:

Step1: Convert all scores to standard form

Elise: $9 \times 10^3 = 9000$
Ryan: $8 \times 10^4 = 80000$
Tiana: $4 \times 10^5 = 400000$
Ben: $60000$
Mari: $200000$

Step2: Order scores from least to greatest

$9000 < 60000 < 80000 < 200000 < 400000$

Step3: Match scores to players

Elise (9000) < Ben (60000) < Ryan (80000) < Mari (200000) < Tiana (400000)

Answer:

Elise, Ben, Ryan, Mari, Tiana
