Explanation:

Step1: Henry's total magazines

To find total, add weekly sales.
$\text{Magazines last week} + \text{Magazines this week} = \text{Total magazines}$

Step2: Frank's parking fee

Fee = hours × rate per hour.
$\text{Hours parked} \times \text{Fee per hour} = \text{Total fee}$

Step3: Sherman's cost per baseball

Divide total cost by quantity.
$\frac{\text{Total cost of package}}{\text{Number of baseballs}} = \text{Cost per baseball}$

Step4: Logan's remaining kittens

Subtract given away from total born.
$\text{Kittens born} - \text{Kittens given away} = \text{Kittens left}$

Step5: Sandra's total transcription time

Multiply time per page by pages.
$\text{Time per page} \times \text{Number of pages} = \text{Total time}$

Answer:

1. Henry: add
2. Frank: multiply
3. Sherman: divide
4. Logan: subtract
5. Sandra: multiply
