Question

Ms. Jones has twice as much invested in stocks as
bonds. Last yeat the stock investments paid 7.5% of
their value while the bonds paid 10% of their value. If
the total that both investments paid last year was
$1,000 how much did Ms. Jones have invested in
stocks?​

Answer 1

Answer:

Let investment in stock be S and bonds be B

So B=2S.

0.075S+0.10B=1000

0.075S+0.20S=1000

Solving S=3636
