Ashopkeeper buys 20 dozen eggs for $80. if 4 dozen eggs are broken and the remaining are sold at $6 per dozen, what is the profit percent on the whole?

20 dozen = 240.
240/80 = $3/dozen

16 dozens left after broken taken out
16 × $6 = $96

He bought $80 and sold for $96

80 ÷ 96 = .833333

Profit Percent = 8.3%

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
