Erin invests $7000 in stocks and bonds. The bonds earn 5% annual interest and the stocks earn 8% interest. If she earns $404 in

Marina CMI [18]

Answer:

$\large \boxed{\$5200}$

Step-by-step explanation:

Let b = the amount invested in bonds

Then 7000 -b = the amount invested in stocks

0.05b = interest from bonds

0.08(7000 - b) = interest from stocks

$\begin{array}{rcll}0.05b +0.08(7000 - b) & = & 404 &\\0.05b + 560 - 0.08b&=&404&\text{Distributed the 0.08}\\-0.03b + 560 & = & 404 & \text{Simplified}\\-0.03b & = & -156 & \text{Subtracted 560 from each side}\\\\b & = & \dfrac{-156}{-0.03} & \text{Divided each side by -0.03}\\\\b & = &\mathbf{5200}\\\\\end{array}\\\text{Erin invests $\large \boxed{\mathbf{\$5200}}$ in bonds}$

People, please answer me.

You are the correct one. If the person is not able to proof, and if you are rather sure about your answer, it is better to take your own answer instead :)

-9d = 63
<Multiply both sides by (-1)>
=> (-1) × (-9d) = (-1) × 63
=> 9d = -63
=> d = -7
