May some one help me with this problem? It's kinda tricky for me. Thanks!Bruce invested in stock paying a10 1/2% dividend. Maya invested $4000 more than Bruce in tax-free bonds paying 7 1/2% annual simple interest. If Maya's income from her investment is $75 more than Bruce's income from his, how much did each invest?

b*.105=B4000*.075=B+75 solve this EQN first300=B+75300-75=B225=B now substitute this value into the first EQN.b*.105=225b=225/.105b=2142.85
