Two investments totallng $47,500 produce an annual income of $3000. One investment ylelds 9% per year, while the other yields 6%
enot [183]

Answer:

The correct answer is "$5000".

Step-by-step explanation:

The given values are:

Two investments totaling,

= $47,500

Annual income,

= $3000

One investment yields per year,

= 9%

Other yield,

= 6%

Let,

  • The amount invested in 9% will be "x".
  • The amount invested in 6% will be "47,500-x".

Now,

⇒  0.09x+0.06(47,500-x)=3000

⇒        0.09x+2850-0.06x=3000

⇒                     0.03x+2850=3000

⇒                                0.03x=150

⇒                                       x=\frac{150}{0.03}

⇒                                       x=5000
