Answer 20

1 bag = 1 * 20 pieces
2 bags = 2 * 20 pieces
3 bags = 3 * 20 pieces

7 bags = 7 * 20 pieces

Answer 21

The 7 bags she figured she needs to buy contain 7 * 20 pieces of candy.
She already has 25 pieces of candy from before, so she needs to add the number of pieces of candy she gets in the 7 bags to the 25 she already had to see if that equals the 165 pieces she needs.
7 * 20 + 25 = 165
