A store's selling price of $ 2240 for a certain computer would yield a profit of 40% of the store's cost for the computer. What selling price would yield a profit of 50% of the computer's cost?

let x be the selling price of the computer.
to yield a profit of 40%, the equation will be

x * 140 /100 = 2240
140x = 224000
x = 1600

Price of the computer in the store is 1600
to yield a profit of 50%

1600 + ( 50 % of the selling price)
= 1600 + 800
= 2400
