Tela earns a base salary of $2200 per month. Once she reaches $41000 in total sales, she earns an additional 5% commission (salary) on the amount of sales over $41000. Let s be the amount of her total sales for the month and N(s) be the amount of her salary for the month. (For instance, if she had sales of $42000 for the month, she would earn a salary of $2200 plus 5% of $1000, since $42000 is $1000 more than $41000.)
