The correct answer is 3) $15
It seems that the first row was before the fixed amount was charged.
Days 1 and 2 are in a constant change of 1x and 15y.
The answer is 1.5 females, one way to solve this is to multiply the probability of a female (50%) with the number of girls in total = 3 multiplied by (50%) = 1.5.
If you are making 15 center pieces per hour, then you are making 3 per hour.
15/5 = 3
Then you divide how many centerpieces you are making by 3.
42/3 = 14
It will take you 14 hours to make 42.
Hope this helps!
