Data set of the variable x and y can be written as a pair of x and y.

That is,

$\left(x,y\right)$

Recall that, the table that shows the cost of buying 1 to 5 pairs of earrings is as follows:

From the above table, data sets are:

$\left(1,29\right),\left(2,58\right),\left(3,58\right),\left(4,87\right),\left(5,116\right)$

In sale, cost of earring of each pair is $29.00 and also buy 2 pairs get 1 pair free.
