Answer 1

Answer:

The amount invested at 9% is $30,000

Step-by-step explanation:

Mardi received an inheritance of $40,000.

Let x be the amount invested at 9%.

So, Amount invested at 10% = 40000-x

Her total annual income from the investments was  $3700.

So, $0.09x+0.1(40000-x)=3700$

$0.09x+4000-0.1x=3700$

x=30000

Hence the amount invested at 9% is $30,000
