Jane averages 143 in her first six bowling games.
Her scores in her next four games are all the same.
If her bowling average over the ten games is also 143,

avg of 10 games is 143, so total of 10 games = 1430
subtract total of 1st 6 games 143 • 6 = 858
need final 4 games to total 1430 – 858 = 572
divided among the 4 final games 572 / 4 = 143 each
