Hello this is the question in the book...
Laurie has $46,000 invested in stocks and bonds. The amount invested in stocks is $8,000 less than four times the amount
invested in bonds. How much does Laurie have invested in bonds?
I set up the equation:
let b= bonds
b + 4b-8000 = 46,000
and I got...
b=10800
however the book has the solution...
b=13500
calculated by: 4b-8000=46000
what I don't understand is this....
if bonds + stocks = 46000
why is the equation set up as
4 x bonds - 8000 = 46000
and not
bonds + 4 x bonds - 8000 = 46000?
thank you
Ken
