Answer:

1.) 90 ways

2.) 15,600 ways

3.) 24 ways

Step-by-step explanation:

1.)  Let's say   we are given 2 digits not equal to each other...The number of different orderings would be  2*1 = 2, or  if we wanted the number of ways to order 2 digits chosen :   10*9 = 90 ways

2.)   The number of ways to arrange 3 letters from 26 letters is:

26 Permutes 3  =    26! / (26 -3)!  =  26*25*24 = 15,600 ways to choose 3 letters in a certain order

3.) 4 different chores.  The number of ways to do them =  4*3*2 *1 = 24 ways

I need help setting up this problem. Please help me out.

Answer:

  12 pounds

Step-by-step explanation:

One quantity is asked for, so it is convenient to let a variable represent that. We can use x to represent pounds of chocolate. Then the total cost of the mix is ...

  19.30·x + 3.50·18 = 9.82·(x +18) . . . . cost of chocolate + cost of trail mix

  9.48·x = 113.76 . . . . . . simplify, subtract 63+9.82x

  113.76/9.48 = x = 12 . . . . . . divide by the coefficient of x

The owner needs to mix 12 pounds of chocolate. (no rounding necessary)
