Example.

If Stefan has 1 bouncy ball, then both of them would probably have 20 balls.

Because, 1 (Stefan's Amount) + 20 (Because 20 MORE.)

* 20 + 1

= 21

Solving Your Problem.

We will do the same thing except replacing "1" with "b".

b + 19 (Hannah's Amount)

b (Stefan's Amount)

b + b + 19

= 2B +19

Note: In Algebra, we use lowercase variables usually...just a side note.
