Sir Donald Bradman had scored 6996 runs in 69 completed test innings. he had one more innings to play. How many runs did he need to score in his final innings in order that his test batting average was greater than or equal to 100? You must write down the inequality that you need to solve, and then solve it. Show all working! (Batting average= Total runs scored divide by total innings completed)
he needs at least 7000 runs to average 100/innings in 70 innings.
6996 + n >= 7000
n >= 4
piece o' cake!
