I think this is the answer, sorry I am not 100% sure
T = 30
A = 4c
A + c = T
Anna Claire has 6 pencils. Times 4 makes Ally's pencil count. 4 * 6 = 24
24 + 6 = 30. So, you answer is: Ally has 24 pencils.
3) Brett arrives 2 hours later than Lionel.
That is the correct answer.
(Sorry, I misinterprated the question before.)
