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%
4 = .25x + 2 , .25x = 2 , x = 8. The answer is D
Add all her phone bills = 115+43+67+95 =320, divide by how many numbers there are, so 4, 320 divided by 4 = 80
