Answer:

Option (4)

Step-by-step explanation:

If we draw a graph against x(Number of months) and y(Number of stamps),

We will get a straight line.

Let the equation of straight line be,

y = mx + b

Here, m = Stamps purchased per month

b = Jasmine was given stamps initially

From the table attached,

m = [tex]\frac{70-65}{2-1}[/tex] = 5 stamps per month

Therefore, equation of the line will be,

y = 5x + b

Since, a point (1, 65) lies on this line,

65 = 5(1) + b

b = 60

That means she was given 60 stamps initially.

Option (4) will be the answer.
