Answer:
Let Craigs age = x
Therefore Dianes age = 25 + x ( since she's 25 years older)
Dianes + Craigs age = (25 + x) + x = 105 (They said both of their ages sums up to 105)
25 + 2x = 105
2x = 80
x = 40
Craigs age is 40 years old.
Dianes age is 65 years old.
10,368 You will ignore the 36 animals in one bag. That number isn't necessary. Ok So you know that one bag weighs 12oz. and 48 bags are in one box. There are 18 boxes in 1 crate so... you are going to do it this way.
12 x 48= 576
576 x 18 = 10,368oz in one crate
so that is your answer.
Hope it is correct.
