Explanation:

Step1: Identify the operation

To find the total time, multiply the time per invitation by the number of invitations. The time per invitation is 5.3 seconds, and the number of invitations is 96.

Step2: Perform the multiplication

Calculate \( 5.3 \times 96 \). We can do this as \( (5 + 0.3) \times 96 = 5 \times 96 + 0.3 \times 96 = 480 + 28.8 = 508.8 \).

Answer:

508.8 seconds
