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?

Multiply the time for one signature by the 96 invitations: 5.3 × 96 = 508.8 seconds. Since the stopwatch measures time to tenths of a second, 508.8 seconds is the most precise determination supported by the measurement. The correct choice is 508.8 seconds.
