Answer:
tina harner scored 733 points
jessica bradley scored 842 points
Explanation:
b + h = 1575
h + 109 = b
plug the second equation into the first
h + 109 + h = 1575
2h + 109 = 1575
subtract 109 from both sides to isolate the variable and its coefficinet
2h = 1466
divide both sides by 2 to get h
h = 733
