mrs. cooper's class has 11 more girls than boys. there are 35 students in all. how many girls are there?

    Sum and difference problems can be readily solved without algebra by the following:

    bigger number = (sum+difference)/2
    smaller number = (sum - difference)/2

    Example, since there are more girls than boys, so
    number of girls = (35+11)/2 = 23
    number of boys = (35-11)/2 = 12
