You work backwards so if half is 41, he had double that before the dog ate half the collection. So he had 82 card after adding 4 new cards so you subtract 4 and your answer is 78 cards.
41 x 2 = 82 82 - 4 = 72
Benny started with 78 baseball cards before his dog ate half of them. We determined this by setting up an equation (x + 4) / 2 = 41 and solving for x, which represents the number of cards before the dog ate them.
The question is asking us to determine how many baseball cards Benny started with before his dog ate half of the collection. To find out, let's assume the number of cards Benny had before his dog ate them is x. According to the information given, after buying 4 new cards and then losing half to his dog, there are 41 cards left. So, the equation we can use is:
(x + 4) / 2 = 41
To find x, we need to solve this equation. Let's multiply both sides by 2 to get rid of the fraction:
2 * ((x + 4) / 2) = 2 * 41
x + 4 = 82
Now, we subtract 4 from both sides to find out the original number:
x = 82 - 4
x = 78
Therefore, Benny started with 78 baseball cards before his dog ate half of them.
Benny started with 78 baseball cards before his dog ate half of them. This was determined by setting up the equation 2 x + 4 = 41 and solving for x . After the calculations, we found that x = 78 .
