Luke purchased a used car for a price of H dollars, which he took to a garage where he bought a new windshield for L dollars, and four new wheels for J dollars per wheel. He then sold the car to a friend for K dollars.
How much profit did he make?
Choices.
A) (K+H)-(L-J)  B) (K-H)-(L+J)  C) (K-J)+(L+H)  D) (K+H)-(L-4J)  E) (K-H)-(L+4J)
The cost for the new wheels= 4J dollars   Then the cost price=H+L+4J dollars   The selling price= K dollars   Hence, the profit= K-(H+L+4J)   = K-H-L-4J dollars   The correct answer is (K-H)-(L+4J)!!
