Bruce invested in stock paying a 10 1/2% dividend.?

Question

Bruce invested in stock paying a 10.5% dividend. Maya invested $4000 more than Bruce in tax-free bonds paying 7.5% annual simple interest. If maya's income from her investment is $75 more than Bruce's income from his, how much did each invest?

Answer 1

0.075(B + $4,000) = 0.105B + $75
0.075B + $300 = 0.105B + $75
0.03B = $225
B = $7,500
M = $11,500
