Answer:
A. $48.75.
Explanation:
We have been given that the minimum monthly payment for Fern's credit card is 2.5% of her balance or $40, whichever is higher.
First of all let us find 2.5% of $1950.



Since the minimum monthly payment will be the higher amount among 2.5% of the balance or $40. As $48.75 is higher than $40, therefore, Fern's minimum monthly payment will be $48.75 and option A is the correct choice.
