D. Is the answer because each shirt costs 12.25. X represents the number. And you subtract it from 3.99 because thats the shipping price.

She bought 'x' number of shirts.

The price of one shirt = 12.25 dollars.

Then total price of all shirts would be '12.25x' dollars.

Given is the shipping charge = 3.99 dollars.

Given is the total bill = 77.49 dollars.

It says no other tax would be charged on this order, so total bill would be sum of total price of all shirts and shipping charges.

Total Bill = Total price of all shirts + Shipping charges.

77.49 = 12.25x + 3.99

Hence, option D is correct i.e. 12.25x + 3.99 = 77.49
