Answer:
Jessica scored 840 points and Tina scored 742
Step-by-step explanation:
Let's use x for Jessica and y for Tina, so Jessica scored 98 more points than Tina, which can be represented by the equation x = y + 98.
Together, they have 1582 points; x + y = 1582.
Substitute the equation, you get:
y + 98 + y = 1582
2y + 98 = 1582
2y = 1484
y = 742
Since x = y + 98, x = 742 + 98/840
