Explanation:

Step1: Analyze the problem

For each question, we need to perform a simple arithmetic operation (addition or subtraction) based on the given information.

Step2: Solve question 1

We have 8 external hard - drives initially and receive 12 more. The operation is addition: \(8 + 12=20\).

Step3: Solve question 2

We have 19 bags of saltwater taffy initially and receive 32 more. The operation is addition: \(19+32 = 51\).

Step4: Solve question 3

We need to mow 30 lawns in total and have mowed 11. The operation is subtraction: \(30 - 11=19\).

Step5: Solve question 4

We need to bake 200 cupcakes in total and have 80 left to bake. The operation is subtraction: \(200 - 80=120\).

Step6: Solve question 5

The full scan takes 95 minutes and has been running for 41 minutes. The operation is subtraction: \(95 - 41=54\).

Step7: Solve question 6

We have 56 customers initially, 8 arrive (add) and 4 leave (subtract). The operation is \(56+8 - 4=60\).
