Eugene has a stamp collection. In one book he has 6 pages with 15 stamps on each page. In another book he has 9 pages with 20 stamps on each page. He gives 25 stamps to a friend. Which of these equations can Eugene use to find how many stamps he has left?

The second one

Step-by-step explanation:

I did it in my head and you don't need to show your work(I assume because it's online)

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
