A store’s selling price for a certain computer would yield a profit of 40 percent of the store’s cost for the computer. If the price were increased by $200, it would yield a profit of 50 percent of the computer’s cost. What was the initial selling price of the computer?
(A) $2000
(B) $2400
(C) $2800
(D) $3000
(E) $3500

If price is increased by 200, incremental increase in profit is 10%. It means that 200 is 10% of the Cost price of the computer. So CP = 2000
Initial SP
