Write and solve to answer the question.

Two baskets of laundry have 28 t-shirts between them. If the smaller basket has 9 t-shirts, how many t- shirts does the larger basket contain?
Let t represent the number of t-shirts in the smaller basket.

O t-9=28; The larger basket contains 31 t-shirts.
O t-928; The larger basket contains 19 t-shirts.
O t+9=28; The larger basket contains 31 t-shirts.
O t+9=28; The larger basket contains 19 t-shirts.

Since the smaller basket has 9 t-shirts, we can set up the equation t + 9 = 28 to represent the total number of t-shirts in both baskets.

Subtracting 9 from both sides gives us t = 19, so the larger basket contains 19 t-shirts.

Therefore, the correct answer is: The larger basket contains 19 t-shirts.
