Answer:Susan's available credit is the remaining credit limit that she has after subtracting her current balance from her credit limit. To calculate Susan's available credit, we can use the following formula:
Available credit = Credit limit - Current balance
Plugging in the given values, we get:
Available credit = $2000 - $284.50
Simplifying the subtraction, we get:
Available credit = $1715.50
Therefore, Susan's available credit is $1715.50.
