Answer:
$30
Step-by-step explanation:
-One week has 7 days, so the total number of eggs laid by both chickens:
[tex]Americana=2\times 7=14\\\\Delaware=1\times 7=7\\\\t=21\ eggs[/tex]
-One doze is equivalent to 12 items. There's only one full dozen unit in 21 pieces.
[tex]Amount =12\times 2.5\\\\=30[/tex]
Hence, she makes $30 in week one.
