Arithmetic Word Problems, 7

Category: Arithmetic

"Published in Newark, California, USA"

You collect baseball cards. Suppose you start out with 15. Maria takes half of one more than the number of baseball cards you have. Since you're nice, you give Peter 1 baseball card. Since his father makes baseball cards, Paul decides to triple your baseball cards. How many baseball cards do you have at the end?

Solution:

The given word problem is about the application of four basic operations. At the start, you have 15 baseball cards. 

One more than the number of baseball cards you have is 15 + 1 = 16 baseball cards. Half of 16 is 8. 

If Maria takes half of one more than the number of baseball cards you have, then you have 15 - 8 = 7 balls.

If you give 1 baseball card to Peter, then you have = 7 - 1 = 6 baseball cards.

Finally, if Paul tripled your baseball cards, then you have 6 x 3 = 18 baseball cards at the end.
