$(n + 8) + (n - 12)$

Expanding the terms,

$n + 8 + n - 12$

Grouping like terms,

$n + n - 12 + 8$

Evaluating the terms,

$2n - 4$

deff fn [24]

question: An investment of $100 is now valued at $149.18 the interest rate is 8% per year, compounded continuously about how long has the money been invested

Answer:

5.2 years

Step-by-step explanation:

Applying

A = P(1+R/100)ⁿ.......................... Equation 1

Where A = amount, P = principle, R = rate, n = time.

From the question,

Given: A = $149.18, P = $100, R = 8%

Substitute these values into equation 1 and solve for n

149.18 = 100(1+8/100)ⁿ

149.18/100 = (1+8/100)ⁿ

1.4918 = (1+0.08)ⁿ

1.4918 = (1.08)ⁿ

Taking the Logarithm of both side

Log(1.4918) = Log(1.08)ⁿ

Log(1.4918) = nLog(1.08)

n = Log(1.4918)/Log(1.08)

n = 0.1737/0.0334

n = 5.2 years.

Uncle Ian spent $59 at a book store. He bought science fiction and mystery novels. The science fiction novels cost $7 apiece and

zzz [600]

Answer:

2 science fiction and 5 mystery

Step-by-step explanation:

First, we will set up a system of equations.

x (science fiction) y (mystery)

x + y = 7 This is the total books bought.

7x + 9y = 59 The amount of each set to the total cost.

Now we solve.

(-7)x + y = 7 equals

-7x - 7y = -49

added to

7x + 9y = 59

this equals

2y = 10

y = 5

Now we know one. We can plug it in to find the other value.

x + 5 = 7

x = 2

You invest $50 in a government bond that says you can redeem it a year later for $54. Use the instructions in Lesson 3 to calcul

Afina-wow [57]

Invested amount in a government bond = $50.

Total returned amount after 1 year =$54.

We need to find the amount of interest earned first.

Amount of intrest earned in a year = Total returned amount after 1 year - Invested amount in the government bond.

Therefore, Amount of intrest earned in a year = $54 - $50.

= $4.

Therefore, earned interest is $4 in an year.

Now, we need to find the intrest rate.

We know the formula,

$Interest \ rate=\frac{Earned \ Interest}{Invested \ Money} \times 100$

Plugging values in above formula, we get

Rate of interest = $\frac{4}{50} \times100$

Dividing 100 by 50, we get 2.

$\frac{4}{50} \times100= 4\times2=8$

Therefore, Rate of Interest (ROI) = 8% per year.
