Richard owned \( n \) cows. Ellis had exactly 4 times as many cows as Richard. Richard buys 13 extra cows. Ellis sells 9 of his cows. Ellis still has more cows than Richard. Form an inequality, in terms of \( n \). Solve the inequality to find the least value of \( n \). You must show all your working.

1) Solve for \( b \) \( -b+10 b+2 b+17=6 \) \( b=\square \)
