Answer 1

`\boxed{\bold{B \ = \ 3,000 \ (1+0.42)^t}}`

Step By Step Explanation:

Goal: Write an equation that can be used to find her balance after 't' years

Deposit: $3,000

Interest: 4.2%

Turn 4.2% Into Decimal

Decimal: 0.42

't': 't' is undefined, so 't' stays the same

Balance = B

Balance = 3,000 Multiplied By 1 + 0.42. That is then multiplied by itself 't' times
