so the money must be $2500.
So, we have two investments, and the profit from both of them should be 5000*0.03=x*0.05=275 total. It means that we'll have $150 from 5k, and we'll still need $125. 0.05x=125, so our second investment will be x=2,5k. I guess trading in Bitcoin Era has its benefits, and making good money is not the only one.
