To find:The total number of songs L has on his computer.
Answer to Problem 15QC
The total number of songs L has on his computer is
Explanation of Solution
Given:
J has 4 times as many songs on her computer as L has on his computer.
J has 516 songs.
Calculation:
Let x be the number of songs L has. Since J has 4 times as many songs than L then multiply x by 4.
Then equate this expression to 516.
Solve by applying the division property of equality.
Conclusion:Therefore, L has 129 songs on his computer.

In a study of how students give directions, forty volunteers were given the task ofexplaining to another person how to reach a destination. Researchers measured thefollowing five aspects of the subjects’ direction-giving behavior:• whether a map was available or if directions were given from memory without a map,• the gender of the direction-giver,• the distances given as part of the directions,• the number of times directions such as “north” or “left” were used,• the frequency of errors in directions.a) Identify each of the variables in this study, and whether each is quantitative orqualitative.
