Answer:

20

Step-by-step explanation:

We can simplify 10/2 = 5

5 = n/4

Multiply each side by 4

5*4 = n/4*4

20 =n

Answer: n = 20

Explanation: To solve for n in this proportion,

we simply use the means-extremes property.

Since 10/2 = n/4, we know that the product of the extremes,

(10)(4), equals the product of the means, (2)(n).

So we know that (10)(4) or 40 equals (2)(n) or 2n.

Dividing both sides by 2, 20 = n.

Paul [167]

Answer:

A\approx\$880.68

Step-by-step explanation:

So, we know that Jolene bought an initial $750.

We also know that the purchase is increasing at an average rate of 5 1/2 %or 5.5%. In other words, this is being compounded.

So, we can use the compound interest formula, which is:

A=P(1+\frac{r}{n})^{nt}

Where A is the total amount, P is the principal value, r is the rate and n is the number of times compounded per year, and t is the amount of years.

So, substitute 750 for P. 5 1/2% is the same as 5.5% or 0.055 (you move the decimal two places to the left and remove the percent symbol) so substitute this for r. Since it's increasing yearly, n is 1. So, our formula is:

A=750(1+0.055)^t

Add:

A=750(1.055)^t

Since the stock was bought 3 years ago, the value <em>now</em> is t=3. So, substitute 3 for t and evaluate:

A=750(1.055)^3

Evaluate. Use a calculator:

A\approx\$880.68

And we're done!
