Di canvases cost $40.00 and she spend half dat amount on paint so she spend 40/2 = $20.00 on paint
She spend $40.00 on canvases, $20.00 on paint and $15.00 on an easel so she spend 40+20+15 = $75.00
She spend $90.00 total and her other purchases total $75.00 so she spend 90-75 = $15.00 on paint brushes

Di final answer: 15.
