    John had some animals. One-fourth were horses, one-half were cows, and the rest were pigs. He had 8 pigs. How many animals did he have altogether?

    Let x = number of animals

    1/4 x + 1/2 x = x - 8

    Multiply both sides by 4.

    x + 2x = 4x - 32

    You should be able to calculate it from here.

    First, if you have a question, it is much better to put it in as a separate post in <Post a New Question> rather than attaching it to a previous question, where it is more likely to be overlooked.

    To some extent, it would depend on the type of batteries you have (D, C, AA, AAA, 9V).

    Since this is not my area of expertise, I searched Google under the key words "rechargable batteries" to get this:

    In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
