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

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
