<PRE><B>Question 100191</B>
A discount store bought 12 dozen radios.  Each to be sold at $15.00 above cost.  The store sold X of the radios at that price.  Each of the remaining radios was sold at $4.00 below cost.  IF the store paid $11.00 for each radio, what was the total income from the sale?
-------------------------------------------
Cost of the radios = 144*11 = $1584 

Income from selling = (11+15)X + (11-4)(144-X)

Total Profit= Income - Cost = 26x+7(144-x)-1584
