A company is looking to cut costs on their monthly office supply purchases. They noticed that if they buy 40% more staplers, the total cost increases by 25%, but if they buy 30% fewer pens, the total cost decreases by 15%. If the total current cost of staplers and pens is $2000, how much do they currently spend on staplers and how much on pens? Let's think step by step and output the final answer within \boxed{}.
