Answer: Gail could have from 0 to 8.5 and Jim could have 10 to 18.5
Step-by-step explanation:
Gail = G
Jim = G + 10
J + G <= 27 ∴
G+10+G <=27
2G + 10 <= 27
2G <= 27 - 10
2G <= 17
G <= 17/2
G <= 8.5
As it is money, let's not say that they have negative money.
So, Gail has from 0 to 8.5. As Jim has 10 more than Gail, he has from 10 to 18.5. At the most : 8.5 + 18.5 = 27.

Ah, yes
if you start with P amount of something and the half life is h units (in years) and the time elapsed is t (in years) then the amount left is A
the equation is
so
given
h=1620
P=150
t=200
so
use your calculator
A≈137.69781917515g
about 138grams left

Answer:
Step-by-step explanation:
we know that
In this problem we have a exponential function of the form
where
y ----> represent the pool’s loss of water
x ----> the number of days
a is the initial value
a=25,700 gal
b ----> is the base
r=15%=15/100=0.15
b=(1-r)=1-0.15=0.85
The function is equal to
