To find the missing tip earnings, we need to calculate the total earnings Yasmine made over 8 nights of work by adding up the listed values and then subtract this total from the total mean earnings over this period.
Total earnings over 8 nights = $35.80 + $79.60 + $38.10 + $20.50 + $10.45 + $96.78 + $45.90 + x
Total earnings over 8 nights = $327.13 + x
Mean earnings over 8 nights = $46 x 8 = $368
$368 - $327.13 = x
x = $40.87
So, the missing tip earnings is $40.87.
