A designer purchased 20 mannequins that each cost an equal amount and then sold each one at a constant price. What was the designer’s gross profit on the sale of the 20 mannequins?

(1) If the selling price per mannequin had been double what it was, the gross profit on the total would have been $2400.
(2) If the selling price per mannequin had been $2 more, the store's gross profit on the total would have been $440.

hi..

let the cost price be x and selling price be y..

so profit will be \(20y-20x=20(y-x)\)
so we require to know y-x
lets see the statements:-

(1) If the selling price per mannequin had been double what it was, the gross profit on the total would have been $2400.
SP = 2y.... so profit = 20*2y-20x=40y-20x=20(2y-x)=2400.....2y-x=120..
various possiblities will give different values for y-x..
insuff


(2) If the selling price per mannequin had been $2 more, the store's gross profit on the total would have been $440.
SP = 2+y....
so profit = 20*(2+y)-20x=40+20y-20x=440.....
20y-20x=400...y-x=20
sufficient
