Jill pays $15,500 for shares in a new company. She sells the shares 8 years later for $12,500. What was her total return on this
nataly862011 [7]

Explanation:

The formula for getting the ROI or Return of Investment is:

ROI=\frac{finalvalue-initialvalue}{initial\text{ value}}\times100

In the problem, the initial value is $15,500 while the final value is $12,500.

Plugging these data into the formula above, we get:

TotalReturn=\frac{12,500-15,500}{15,500}\times100

Then, simplify.

\begin{gathered} TotalReturn=\frac{-3,000}{15,500}\times100 \\ TotalReturn=-0.193548\times100 \\ TotalReturn=-19.3548 \\ TotalReturn\approx-19.4\% \end{gathered}

Answer:

The total return on Jill's investment is -19.4%.

Anettt [7]
We need to construct the system of equations in order to solve that problem. Let's denote one-time membership fee with x and monthly fee with y. Then we can write that John paid x+6y=325 and Abigail paid x+9y=475. Solving the system of equations \left \{ {{x+6y=325} \atop {x+9y=475}} \right., we find that x=25 and y=50. The monthly fee is 50 dollars.

gulaghasi [49]

Answer:

1) (2x + 2)(x + 2)

2)  2(x + 1)(x - 1)

3) (x^2 + 3)(x^2 - 3)

4) 2x(x + 5)(x - 2)

5) (5x + 2y)(5x - 2y)

Step-by-step explanation:

1)

2x^2 + 6x + 4

= 2x^2 + 4x + 2x + 4

= 2x(x + 2) + 2(x + 2)

= (2x + 2)(x + 2)

2)

2x^2 - 2

= 2(x^ 2 - 1) (The difference of two squares)

= 2(x + 1)(x - 1)

3)

x^4 - 9 (The difference of two squares)

=(x^2 + 3)(x^2 - 3)

4)

2x^3 + 6x^2 - 20x

= 2x(x^2 + 3x - 10)

= 2x(x + 5)(x - 2)

5)

25x^2 - 4y^2         (The difference of two squares)

= (5x + 2y)(5x - 2y)
