Danny collects bottle caps and wrappers. He found 15 bottle caps and 18 wrappers at the park. Now he has 67 wrappers and 35 bottle caps in his collection. How many more wrappers than bottle caps does danny have now?
First, we need to find the total number of bottle caps and wrappers that Danny found at the park. 15 bottle caps and 18 wrappers is the same as 15 + 18 bottle caps and wrappers, so we can say that Danny found 33 bottle caps and wrappers at the park. 

Next, we need to find the total number of bottle caps and wrappers that Danny has in his collection now. 67 wrappers and 35 bottle caps is the same as 67 + 35 bottle caps and wrappers, so we can say that Danny has 102 bottle caps and wrappers in his collection now. 

Now, we need to find the difference between the total number of wrappers and the total number of bottle caps. The total number of wrappers is 102 and the total number of bottle caps is 35, so the difference is 102 - 35, which is the same as 67. 

Therefore, Danny has 67 more wrappers than bottle caps now. 

Therefore the answer (numeric) is: 

67
