Solution: 1 - The question is: “How many girls attended the party? ” 2

Solution: 1 - The question is: “How many girls attended the party? ” 2 - Let x = the total number of students attending the party Let y = the number of boys attending the party Let z = the number of girls attending the party 3 - The given fact that 48 percent of the students are boys has no effect on the problem and may be discarded. 4 - The relationships stated are: a. 70 percent of the students attended ( x ) b. 60 percent of those attending were boys ( y ) c. This implies that the difference between x and y represents the number of girls attending (z). So, we express these relationships as the following equations: a. x = 1000 * 0. 70 b. y = x * 0. 60 c. z = x – y 5 - Since the variable x must be known to find the variable y and both x and y must be known in order to find z, the equations must be solved in the given order.
