It will be b because you will have to time $3.50P140= 490
4x+3(2x-1) -4x 3(2x-1)= 6x-3 -4x 4x+6x-4x= 6x-3
Okay so subtract 50 from both sides and you would get 360=90x and then divide each side by 90 and you would get x= 4 so it took 4 hours
I would say smaller than because you would be dilating the image by a number less than 1, which is making the image smaller.
