Question 1005146: Let set C = {even numbers between 1 and 99} and set D = {numbers between 1 and 150 that are evenly divisible by 10}.
What is C ∩ D? (2 points)
{10, 20, 30, 40, 50, 60, 70, 80, 90} is the answer but I don't know why

You can put this solution on YOUR website! C intersect D asks you to find which numbers are in BOTH sets.
For a number to be divisible by ten, it means it ends in a zero.
All those even numbers ending in zero between 1 and 99 are
{10, 20, 30, 40, 50, 60, 70, 80, 90}
