Answer:
7hours and 16 minutes
Step-by-step explanation:
8:15-9:15 is one hour. 9:15-10:15 is two hours. 10:15-11:15 is three hours.11:15-12:15 is four hours. 12:15-1:15 is five hours. 1:15-2:15 is six hours. 2:15-3:15 is seven hours. 3:15-3:31 is 16 minutes.
So each batch makes 14 pieces
and she need 8 dozen (dozen=12) so 8 dozen=8*12=96
so 14 pieces per batch
needs 96 pieces
x=number of batches
14 times x=96
14x=96
divide both sides by 14
x=96/14
96/14= aprox 6.86
but you normally can't make a fraction of a batch so she need to make 7 batches at the least
1 dozen eggs = 12 eggs
1.35 / 12 = 0.1125.....so the unit cost = $ 0.11 (11 cents) per egg
Number 1 is YES
Number 2 is YES
Number 3 is no
