When you write a function in the form
, y is the dependent variable, and x is the independent variable.
So, if b is the independent variable, it means that we have to solve the expression for r.
To do so, we perform the following steps: start with

Add 12 to both sides

Divide both sides by 4:

So, we wrote the expression in the form
, which means that r is the dependent variable and b is the independent variable, as requested.
There are two so I'll give you the answer to both! 4,000 and 400
Each year it will gain $10 so it will take 50 years.
1,000 × .02 = 20
1,000 ÷ 20 = 50
