The first thing we must do for this case is to define variables:
 x: text messages
 Y: pictures
 We write the system of equations:
 0.05x + 0.10y = 4
 x = y + 5
 Solving the system we have:
 x = 30
 y = 25
 Answer:
 
you send:
 
30 text messages
 
25 pictures

F=P(1/2)^(t/h)
F=future amount
P=present amount
t=time elapsed
h=legnth of half life

P=96
t=2
h=1
F=96(1/2)^(2/1)
F=96(1/2)^2
F=96(1/4)
F=96/4
F=24 grams



grow by 35%
compound interest
F=P(1+rate)^time
F=95000(1+0.35)^10
F=95000(1.35)^10
F=95000(20.106555868618)
F=1910122.9075187

there would be a 99% chance of a red marble being pulled out or even a 1% chance.

because of their being five green marbles and six red there is always a chance you could pull out any one of the colors.

but i believe that both of the answers are 1/2

but im not 100% sure
