If x is equal to the sum of the integers from 20 to 40, inclusive, and y is the number of even integers from 20 to 40, inclusive, what is the value of x + y?	Choose the correct choice
A) 601  B) 611  C) 621  D) 631  E) 641
x = 20 + 21 +...+ 40 = 21(30) = 630   y = 11   x+y = 641   The answer is 641.
