Which expression is the coefficient of the n term -1

C. -2n² - n + 5

Step-by-step explanation:

In expression C, the coefficient of the n term is -1;

  The expression in choice C is given as:

               -2n² - n + 5

The coefficient is the number before a variable;

  For n², the coefficient is -2

    for n, the coefficient is -1

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
