Quick Check Solutions Exponential Functions Target D
This problem can have different answers because your age will determine what value you use for time, \( t \). For this particular example, let's assume that you are \( 14 \) years old and that your friend is \( 15 \) years old. The key word in the problem that leads you to know this is a growth function is "earns", so when writing the exponential growth function for this problem, use addition and not subtraction.
If you are \( 14 \) and your friend is \( 15 \), then your friend would have more money in their account when they reach \( 17 \) years old. But as stated above, this problem will vary depending on the age of you and your friend.
