5-12.

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

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

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

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.

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?

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