Enlarge shape A by scale factor 0.5 with centre of enlargement (0, 0). What are the coordinates of the vertices of the image?

So don't take my word i'm not exactly a mathematical person but i would assume a. because while selling the soap every month you increase in sells so you would by 11 percent. the you would get the factor 0.89 which if i had to guess would be the monthly profit over 11 probably wrong tho
