You collect pens. Suppose you start out with 7. Mike gives you another
22 pens. Since her father makes pens, Cindy decides to double your pens.
Since you're nice, you give Sharon 19 pens. How many pens do you have
at the end?
Solution:
The given word problem is about the application of four basic operations. At the start, you have 7 pens.
If Mike gives you 22 pens, then you have 7 + 22 = 29 pens.
If Cindy doubles your pens, then you have 29 x 2 = 58 pens.
Since you're nice, you give Sharon 19 pens. Therefore, you have 58 - 19 = 39 pens left at the end.
