Answer:
11
Step-by-step explanation:
n(A) means the number of elements in set A
Element 1=-10
Element 2=-9
Element 3=-8
Follow the pattern
Element 4=-7
Element 5=-6
Element 6=-5
Element 7=-4
Element 8=-3
Element 9=-2
Element 10=-1
Element 11=0
There are 11 elements in set A.
Also this has the same number of elements as {0,1,2,...,8,9,10} which has (10+1) elements.

Step-by-step explanation:
let E be weight of expensive nuts, C be cheaper nuts
E*8+C*5=10*6 value equation
E+C=10 mass equation
Solve it by any method, I will do determinants
Det: 8-5=3
E= (60-50)/3=10/3 =3.33 lb
C= 80-60 /3=20/3 =6.66 lb
Answer:
the correct answer is C
