Given:Â
Total winnings = $700000
 Rate on utility bond = 80% per year
 Rate on savings account = 20% per yearÂ
 To find: Funds to be allocated to each investment so as to get same income from both investments.Â
 Solution:Â
 Let the amount invested in utility bonds be x.
 Let the amount invested in savings account be y.
Â
 We get equations as below,Â
 x + y = 700000Â
 y = 700000 - xÂ
 0.80x = 0.20yÂ
 Putting value of y in the formula, we getÂ
 0.80x = 0.20 (700000-x)
 0.80x = 140000 - 0.20x
 x = 140000Â
 x = $140000
 y = $700000 - xÂ
 y = $700000 - $140000Â
 y = $560000
  So, in order to get same income from both the investments $140000 should be invested in utility bonds and $560000 should be invested in savings account.
