If the interest is the same for both accounts then:
.03x=.05(16000-x)
.03x=800-.05x
.08x=800
x=10000, since the interest is the same for both we can just double the interest from one investment to find the total interest earned each year...
.03(10000)2=$600.00
B and A if Im not wrong hope I didn’t get it wrong
7/5 x 7/1 = 49/5 or 9 4/5
