Represent the above data in tabular form, as shown below.

Among the choices, graph-2 suits the result.

In the graph, x-axis represents Weights of apples and y-axis represents the cost of apples.

From, the graph the cost of 12 lbs apples is $ 48.

So, James has to pay $ 48 for 12 lbs of apples.

Cost of a pair of jeans = $8

Cost of n pairs of Jeans= $8× n

The following table shows the total cost for the corresponding number of pairs of Jeans.

The points plotted in Graph 1 are same as the values obtained in the table.

Graph 1 shows the relationship between the number of pairs of Jeans and the total cost.

Cost of a Pen= $0.50

Cost of n Pens = $0.50× n

The following table shows the total cost for the corresponding number of Pens.

The points plotted in Graph 4 are same as the values obtained in the table.

Graph 4 shows the relationship between the number of pens and the total cost.

Cost of 2 boxes of Crayons = $1.5

The following table shows the total cost for the corresponding number of boxes of Crayons.

The points plotted in Graph 3 are same as the values obtained in the table.

Graph 3 shows the relationship between the number of boxes of crayons and the total cost.

1 foot = 12 inches

Make a table of values for this relation.

Plot the values on a coordinate plane and join the points.

The graph looks like the one below.

So, Graph 1 shows the relation between the number of feet and the number of inches.

The number of bolts produced by the machine in 1 hour = 15003 = 500.

As the time goes on, the total number of bolts produced by the machine, increases.

The direct variation between the number of bolts produced by the machine and the time taken can be given as, number of bolts produced in x hours is 500 × x.

The number of bolts produced and the time taken is shown in the table.

Graph 4 shows the relationship between the number of bolts produced by the machine and time taken.

As the number of workers increase, the time taken by them to finish the job decreases.

Inverse variation is a relationship between two variables, in which, the product is a constant. When one variable increases the other decreases in proportion, so that the product is unchanged.

Therefore, Graph 4 shows the relation between the number of workers and the time taken by them to finish a particular job.

In the graph, the x-axis represents the number of chocolates and the y-axis represents its cost.

From the graph, cost of 16 chocolates is $4.

So, Laura has to pay $4 to buy 16 chocolates.

In the graph, the x-axis represents the number of minutes and the y-axis represents the number of words typed.

From the graph, the number of words typed in 7 minutes is 210.

So, Jim typed 210 words in 7 minutes.

Volume of a sphere V = 43πr3

Make a table of values for the volume V = 43πr3.

r	43 πr3	V	(r, V)
1	43 (3)(1)3	4	(1, 4)
2	43 (3)(2)3	32	(2, 32)
3	43 (3)(3)3	108	(3, 108)
4	43 (3)(4)3	256	(4, 256)

Graph the ordered pairs as shown.

Graph 4 matches the above graph.

So, Graph 4 best represents for the volume of a sphere with radius r.

Let a, t represent the amount earned and the time respectively.

At t = 1, a = 25(1) = 25

At t = 2, a = 25(2) = 50

At t = 3, a = 25(3) = 75

At t = 4, a = 25(4) = 100

At t = 5, a = 25(5) = 125

Represent the above data in tabular form, as shown below.

Input (t)	1	2	3	4	5
Output (a)	25	50	75	100	125

Among the choices, Graph 1 suits the result.

Let n, c represent the number of hotdogs bought and the total cost respectively.

At n = 1, c = 3(1) = 3

At n = 2, c = 3(2) = 6

At n = 3, c = 3(3) = 9

At n = 5, c = 3(5) = 15

At n = 4, c = 3(4) = 12

Represent the above data in tabular form, as shown below.

Input (n)	1	2	3	4	5
Output (c)	3	6	9	12	15

Among the choices, Graph 3 suits the result.

Locate 16 on the vertical axis. Follow the horizontal line through 16 till the line meets the graph at P (say). From P take a vertical line to meet the horizontal axis. This meeting point gives the time it takes to discharge 16 liters of water i.e. 8 minutes..
