Answer:
18
Explanation:
lets go step by step.
the function called tryIt has a value, a variable named "a". this "a" variable will be whatever the user enters when the program says, Enter a number.
ok so if we enter "a" as 2, and b in the function will always be 7, and 2 + 7 equals 9,
and the ans variable (short for answer) will take the result of the function (9) and multiply it by 2,
then the answer is 18
