Gary had $192.

Step-by-step explanation:

Let Gray has the money = $x

Gray spent on a watch = $48

Remainder money = $(x - 48)

He spent one third of the remainder on a pen.

Money spent on a pen =

This remainder money is the half of x then the total money spent

x = 6×32

x = 192

Money left after spending on watch = 192 - 48 = $144

Money spent on a pen = = $48

Money left = 144 - 48

                 = $96

This amount is half of the total money =

                                                               = $96
