Question

The tables shows the total number of customers at a car wash after 1, 2, 3, and 4 days of its grand opening. Which graph could represent the data shown in the table?

Answer 1

The correct answer is:

Graph A.

Step-by-step explanation:

We can eliminate the last two graphs as they decrease; the numbers in this table continually increase.

To determine if it is graph A or graph B, we look at the spacing between the points. In the first graph, there is a steep jump between the first two points. The next two points increase more slowly, and there is another jump between the last two.

In the second graph, there is a slight increase between each pair of points. This does not match the data in the table; the first two points increase from 61 to 125, whereas the next two points go from 125 to 177, which is a smaller increase. This means the correct graph is graph A.

Answer 2

Let

`A(1,61) B(2,125) C(3,177) D(4,242)`

Using a graph tool

see the attached figure N 1

therefore

the answer is the option A
