Answer:
[tex]A=42000(1.04)^n[/tex]
Step-by-step explanation:
This is a compound interest formula expressed as:
[tex]A=P(1+i)^n[/tex]
Where
- [tex]n[/tex] is time in years
- [tex]i[/tex] is the rate of interest
- [tex]A[/tex] is the accumulated amount after n years
- [tex]P[/tex] is the initial amount.
#We substitute the given values to determine amount after n years as follows:
[tex]A=P(1+i)^n\\\\=42000(1+0.04)^n\\\\=42000(1.04)^n[/tex]
Hence, the amount earned after n years of her career is given by [tex]A=42000(1.04)^n[/tex]
