# Two accounts

Two accounts in the bank, one per year interest 2%, the second 3%. Total interest income 1900 USD. If interest rates were reversed, the yield would be USD 200 higher. What are the amounts on each account?

a =  50000
b =  30000

### Step-by-step explanation:

0.02a + 0.03b = 1900
0.03a + 0.02b = 1900+200

0.02•a + 0.03•b = 1900
0.03•a + 0.02•b = 1900+200

0.02a+0.03b = 1900
0.03a+0.02b = 2100

a = 49999.999999
b = 30000
