Tasha only has $\$3$ saved but has a goal of doubling the total amount of money she has saved every month.

1. Write an equation for the total amount of money Tasha has saved after $x$ months.

   Answer (a):

   $T(x) = 3(2)^x$

2. Tasha’s brother Clifton is going to copy Tasha’s savings plan exactly, but because he wants to always have more money than her, so he has $\$10$ saved and hiding in his dresser. Write an equation for the total amount of money Clifton has saved after $x$ months.

   Hint (b):

   How can you show the $\$10$ more than Tasha's savings plan?
   

3. Graph each situation on the same set of axes. How do the graphs of the two equations compare?

   Answer (c):

   Clifton's graph is $10$ units above Tasha's graph.
