Hi All,
We're told that a retailer purchased eggs at $2.80 per dozen and sold the eggs at 3 eggs for $0.90. We're asked for the retailer's gross profit from purchasing and selling 5 dozen eggs(1 dozen eggs = 12 eggs). There are a couple of different ways to go about doing the work here (and a certain amount of Arithmetic is required).
Since 3 eggs are sold for $0.90, we know that a dozen eggs will be sold for (4)($0.90) = $3.60.
Thus, each dozen eggs sold will yield a PROFIT of $3.60 - $2.80 = $0.80.
With 5 dozen eggs, the profit will be (5)($0.80) = $4.00
Final Answer: C

We see that the retailer sold each egg for $0.90/3 = $0.30, and hence sold the eggs for $0.30 x 12 = $3.60 per dozen. Thus, the profit per dozen of eggs is 3.60 - 2.80 = $0.80, and so the gross profit for 5 dozen eggs is 0.80 x 5 = $4.00.BTGmoderatorDC wrote:A retailer purchased eggs at $2.80 per dozen and sold the eggs at 3 eggs for $0.90.

SP of one dozen= 0.9*4= 3.6
Profit per dozen= 3.6-2.8= 0.8
So, for 5 dozen= 0.8*5=4
