The table below shows the total cost of admittance to a basketball game, y, for x students.xy5$2510$5015$7520$100Which explains how the table can be used to predict the cost of any number of students attending the game?
Answer
A
The table is a partial representation of a larger data set. It can be used to generate a graph that is a complete representation of the data set.
B
The table is a partial representation of a larger data set. It can be used to generate an equation that is a complete representation of the data set.
C
The table is a complete representation of the data set. To determine the cost of any number of students, find the number of students in the x-column.
D
The table is a complete representation of the data set. To determine the cost of any number of students, find the number of students in the y-column.
Explanation
The table lists only a few numbers of students, so it is a partial representation. Each student adds $5 to the total cost: for example, 5 students cost $25 and 10 cost $50. The equation y = 5x represents the pattern and can predict the cost for any number of students, so choice B is correct.
