Answer:
710%
Step-by-step explanation:
1 bucket of eggs is charged at $16.20 for 450 eggs.
1 dozen = 12
450 = 450/12 = 37.5
The store pays ($16.20/37.5 doz)=$0.432/doz
The store charges ($3.50-0.432) $3.068 more per dozen than they paid.
($3.068/$0.432)(100%) = 710%

Answer:
-1ab^2 + 5b + 8
Step-by-step explanation:
3a^2+9ab+5-4a^2-4ab+3

9ab-4ab=5ab
5+3=8
-1ab^2+5ab+8
