• jackson invests $1000 in a bank with a 5% annual interest rate. this situation shows
• april figured out that the value of a car decreases by a fixed amount of $800 per year. this situation shows
• maggie observes that the amount of a radioactive substance decreases by 2% per day. this situation shows

Explanation:

1. For Jackson's investment: The value grows by a percentage of the current amount each year, which fits exponential growth.
2. For April's car value: It decreases by a fixed dollar amount annually, which is linear change, not exponential.
3. For Maggie's radioactive substance: The amount decreases by a percentage of the current quantity each day, which fits exponential decay.

Answer:

• Jackson invests $1000 in a bank with a 5% annual interest rate. This situation shows exponential growth
• April figured out that the value of a car decreases by a fixed amount of $800 per year. This situation shows neither
• Maggie observes that the amount of a radioactive substance decreases by 2% per day. This situation shows exponential decay
