A dealer gives a 25 percent discount on the list price of a radio and still makes 40% profit on the cost price of the radio .if the cost the radio is 30$ then what is the list price of the radio .
Hi bluffmaster.roy.007
let :
x = the list price of the radio
y = the cost the radio = $30
The dealer gives a 25 percent discount on the list price of a radio ----> he sells it with price 0.75 x
still makes 40% profit on the cost price of the radio -----------------------> he gets 1.4 y
Can you continue ?
