I had no idea what to do for d (ii)
I just did 0.4 x 10 = 4m = 4L LOL I'm pretty sure that's not correct.

Oh crap. I think I understand now.. is it 4m, so thus we divide our answer in (i) by 3?!?! ok no idk.

How many tiles would Jay use altogether to make to first 20 rows
I got 2440 to begin then got 440 haha
i forgot my answer but you use Sum of AP.
a = 3 d=2

T(20) = 3 + 2(19) = 41
S(20)=10(44) = 440
