A man invests x amount of money at 2% interest. The next day he invests $800 more than the previous morning into an account that earns 4% interest. At the end of one year he has earned a total of $112 in interest. How much money was invested in each account?

Which of the following equations could be used to solve the problem?

0.02x + 0.04(800) = 112
0.02x + 0.04(x + 800) = 112
0.04x + 0.02(x + 800) = 112
0.04x - 0.04(x + 800) = 112
