The total amount of money earned after 15 years is given by the formula: A=p(1+r/100)^n where: p=principle=$2000 r=rate=6% n=time=15 years thus; A=2000(1+6/100)^15 A=2000(1.06)^15 A=$4,793.12
There is no x-intercept in the equation. This means that Aster has no base pay, or no starting pay. So all of her earnings only depend on x amount of car sales.
