n(A) is the number of elements is A, sometimes written |A|. I count 7. n(A)=7
13 is among the elements of A, so 13 ∈ A is TRUE
26 is among the elements of A, so 26 ∉ A is FALSE
10 isn't in A, so 10 ∉ A is TRUE

Answer:
A. 40.021
Step-by-step explanation:
Unlimited calls = $40
Text message = $0.021
NOTE:There is a difference between the value you gave for cost of text messages in the question and the values given in the group of answers. I will use $0.021 for cost of text messages since it is common to all answer choices.
Total cost = Cost of unlimited calls + cost of text messages
C = $40 + $0.021
= $40.021
Therefore, the equation which represent the total cost in dollars for a month is 40.021
A. 40.021
The values of the number is 43
x+21=64
subtract 21 on each side
x = 43
