lola needs to sign 96 invitations. using a stopwatch that measures time to tenths of a second, it takes lola 5.3 seconds to sign her full name. going by the accuracy of the stopwatch, which is the most accurate determination for the number of seconds lola needs to sign all 96 invitations? 508 seconds 509 seconds 510 seconds 508.8 seconds

Explanation:

Step1: Identify the formula

To find the total time, we use the formula: Total Time = Time per invitation × Number of invitations.

Step2: Plug in the values

Time per invitation is \( 5.3 \) seconds, and the number of invitations is \( 96 \). So we calculate \( 5.3\times96 \).

Step3: Perform the multiplication

\( 5.3\times96=(5 + 0.3)\times96 = 5\times96+0.3\times96 = 480+28.8 = 508.8 \) seconds.

Answer:

508.8 seconds
