Step-by-step explanation:
<span>(a) you can show the concentration by:
amount of salt / amount of water
amount of salt
= 30g / L
= [ 30 * 25g ] / [ 25L ] , 25L = 1 min
= [ 30 * 25g ] / min
amount of water
= 5000 + 25t
[ 30 * 25t ] / [ 5000 + 25t ]
= [ 30 * 25t ] / 25*[ 200 + t ]
= 30t / [ 200 + t ] yeah
(b)
lim t->∞ [ 30t / ( 200 + t ) ]
= lim t->∞ [ ( (1 / t) * 30t ) / ( (1 / t) * ( 200 + t ) ) ]
= lim t->∞ [ 30 / ( (200 / t) + 1 ) ]
= 30 / ( (200 / ∞) + 1 )
= 30 / 1
= 30

D be it’s all the great number for it
I added 8 on both sides to get 12=3x then I divided by 3 on both sides to get x=4
