Respuesta :
The amount that Greg spent on the comic book is; $17
Let the amount of money he had initially be x.
Thus, if he spent ⅔ of that initial amount, it means the amount he will have left is;
Amount left = x - ⅔x
Amount left = ⅓x
Since he had $8.5 left, then;
⅓x = 8.5
x = 3 × 8.5
x = $25.5
Thus;
Amount he spent on the comic book is;
⅔ × 25.5 = $17
