Using what you know about variables and re-assignment you should be able to trace this code and keep track of the values of a, b, and c as they change. You should also have a sense of any possible errors that could occur.

Explanation:

The missing program is given below

var a = 3;

var b=7;

var c = 10;

a=a+b;

b=a+b;

c=a+b;

console.log("a:" + a + "b:" + b+"c:" + c);

In the program  a is assigned a value 3, b is assigned a value of 7, c is assigned a value 10;

a = a+ b; so here a = 3+7 = 10. New value of a = 10

b = a+b; so here b=10+7 = 17. New value of b = 17

c = a+ b; so here c = 10 + 17 = 27. New value of c = 27

So the final line will log a = 10, b = 17, c = 27.

the answer would be 2

since they are only saying that the couple has 20 daughters and so on but they never said that they went to the movies as well therefore the couple was the only people that went to the movies.

hope this ! : 3

i think the answer is a or d
