Assume that you have a large sample of radioactive atoms, arranged in a rectangular lattice. Imagine that this lattice has some

number of rows and columns, with an atom in each lattice-position.
Now, in this scenario, the atoms do *NOT* decay independently. Instead, each row and column of atoms decays independently. More specifically, imagine that each row of atoms decays as a random variable, independently of all other rows and columns. Say that the probability of any particular row decaying over the course of one hour is 10%. In addition, each column of atoms decays as a random variable, independently of all other rows and columns
Say that the probability of any particular column decaying over the course of one hour is 40%.
Can you make a model for how the total number of atoms decays?
Make a graph/plot of your model, illustrating the amount of radioactive material you expect as a function of time in hours).
Does the total number of atoms decay exponentially?
If so, can you define a decay rate for the total number of atoms?

A music website charges x dollars for individual songs and y dollars for entire albums. Person A pays $25.92 to download 6 indiv
kati45 [8]
Amount charged for downloading individual songs = x dollars
Amount charged for downloading an entire album = y dollars
In respect to person A:
6x + 2y = 25.92
3x + y = 12.96
y = 12.96 - 3x
In respect to person B:
4x + 3y = 33.93
Putting the value of y from the first equation in the second, we get
4x + 3(12.96 - 3x) = 33.93
4x + 38.88 - 9x = 33.93
- 5x = - 4.95
x = 0.99 dollars
Putting the value of x in the first equation, we get
y = 12.96 - 3x
   = 12.96 - 2.97
   = 9.99 dollars
