Amount to be invested in 5%5% interest bond is x= $12500x=$12500
Amount to be invested in 7%7% interest bond is x= $2500x=$2500

Explanation:

Let $x$x be the amount invested in 5%5% interest bond.
Then $(15000-x)$(15000−x) is the amount invested in 7%7% interest bond.
By condition 0.05*x + 0.07*(15000-x) =800 :.
0.05x-0.07x+1050=800 or 0.02x =250 or x= $12500 :. 15000-x=15000-12500=$2500
The amount to be invested in 5% interest bond is x= $12500
The amount to be invested in 7% interest bond is x= $2500[Ans]
