The image of p is (-1, 1)
Because the rule for 270 counterclockwise is (y,-x)
78, because you have to do the inverse operation so 80/2= 40 then 40-1= 39 and 39*3 = 78
8*4
I hope that helps !
So, 4*4*4*4 = 16+16 which is 32
2nd month: (2000 - 35) 1.01 = 1984.65
3rd month: (1984.65 - 35) 1.01 = 1969.15
