Ebony but a four year treasury note that pay the equivalent of 3.8% simple interest. She invested $3000 more in a 9 year bond e

Anastasy [175]

Treasury bond's invested amount is "$7000" and Bond's invested amount is "$10000",

Let,

The amount invested in treasury note will be = x
The amount invested in bond will be = (x + 3000)

then,

→ $\frac{x\times 4\times 3.8}{100} +\frac{(3000+x)\times 9\times 4.6}{100}=5204$

→ $\frac{15.2x}{100}+\frac{(3000+x)\times 41.4}{100} =5204$

→ $\frac{15.2x}{100} +\frac{124200+41.4x}{100} =5204$

→ $\frac{15.2 x+124200+41.4x}{100} = 5204$

→ $56.6x+124200=520400$

→ $56.6x=520400-124200$

→ $56.6x=396200$

→ $x = \frac{396200}{56.6}$

→ $= 7000$

Amount invested in bond will be:

= $x+3000$

= $7000+3000$

= $10000$

Thus the above is the correct answer.

Answer:

The answer is $668.00

Step-by-step explanation:

Just add 200 to how much you will pay over time. So first multiply 39 by 12 (12 months in a year, 39 per month,) to find out how much you will pay by the end of the year then add 200 to that.
