Worksheet with multi-step word problems for math practice.

Here are the step-by-step solutions for the problems on the worksheet.

1. Sandra, Deacon, and Breanna's Books
* Step 1: Add up all the books read by each child individually.
$5 + 6 + 7 = 18$ total books counted.
* Step 2: Account for the overlap. The problem says one book was read by all three children. This means that single book was counted 3 times in our total above (once for Sandra, once for Deacon, and once for Breanna). To find the number of *different* books, we need to remove the extra counts.
* Step 3: Subtract the duplicates. Since the shared book was counted 3 times but should only be counted once, we subtract 2 from the total.
$18 - 2 = 16$.
*(Alternatively: Each child has unique books plus the 1 shared book. Sandra has 4 unique, Deacon has 5 unique, Breanna has 6 unique. $4 + 5 + 6 + 1 \text{ (shared)} = 16$.)*

2. Science Class Test Tubes
* Step 1: Start with the total number of test tubes needed: 8.
* Step 2: Subtract the tubes used for the first experiment: 2.
$8 - 2 = 6$ test tubes remaining.
* Step 3: The remaining 6 tubes were split evenly between the other two experiments.
$6 \div 2 = 3$.

3. Branson and Beatrice's Fruit Salad
* Step 1: Calculate their total allowance. They each had $\$7$, so:
$7 + 7 = \$14$.
* Step 2: Subtract the cost of the movie ticket.
$14 - 12 = \$2$ remaining.
* Step 3: Determine how many containers they could buy. Each container costs $\$1$.
$2 \div 1 = 2$ containers.
* Step 4: Split the containers evenly between the two siblings.
$2 \div 2 = 1$ container each.

4. Cam's Typing Speed
* Step 1: Calculate how many words Cam could type in 5 minutes *before* breaking his arm.
$9 \text{ words/minute} \times 5 \text{ minutes} = 45$ words.
* Step 2: Calculate how many words he could type in 5 minutes *after* breaking his arm.
$6 \text{ words/minute} \times 5 \text{ minutes} = 30$ words.
* Step 3: Find the difference between the two amounts.
$45 - 30 = 15$ words.

5. Gisselle's Bicycle Savings
* Step 1: Calculate how much money Gisselle saved. She saved $\$6$ a week for 8 weeks.
$6 \times 8 = \$48$.
* Step 2: Compare her savings to the cost of the bicycle ($\$50$).
$\$48$ is less than $\$50$, so she did not have enough.
* Step 3: Calculate how much more she needs.
$50 - 48 = \$2$.
She had $\$2$ too little.

6. Annie and Dustin's Programming Course
* Analysis: This problem asks for a specific number of hours ("How many hours do you think they spent...") but does not provide the necessary data to calculate an exact answer (such as how many weeks they worked or how many hours per day).
* Conclusion: As written, this problem cannot be solved mathematically because information is missing. In a real classroom setting, this might be an estimation question where you make up reasonable numbers (e.g., "If they worked 4 hours a day for 4 weekends, that would be 32 hours"), but there is no single correct mathematical answer based strictly on the text provided.

Final Answer:
1. 16 different books
2. 3 test tubes
3. 1 container each
4. 15 words
5. No, she had $2 too little.
6. Cannot be solved exactly (missing information)
