Explanation:

Step 1: Calculate the total cost of the tickets and the book

The cost of an adult ticket is \( \$11.25\), the cost of a child ticket is \( \$5.75\), and the cost of the book is \( \$3.99\).

• Add the cost of the adult ticket and the child ticket: \(11.25 + 5.75=\$17\)
• Then add the cost of the book: \(17+3.99 = 20.99\)

Step 2: Compare the total cost with the amount of money Mrs. Cooper has

Mrs. Cooper has \( \$20\).

• Compare \(20\) and \(20.99\). Since \(20<20.99\)

Answer:

No, Mrs. Cooper cannot buy a museum ticket for herself, a ticket for her daughter, and a book. Because the total cost \(20.99\) dollars is more than the \(20\) dollars she has.
