$ 65 is marked up to $70.20

olganol [36]

You can work out the difference between the numbers by taking the smaller one away from the larger one:
70.20 - 65 = 5.20

Then you can divide the difference (5.20) by the original number (65) to get how many percent it is of 65 in decimal form:
5.20/65 = 0.08

Then you can times it by 100, to get the percentage:
0.08 * 100 = 8%

This means there was a 8% price increase in $65 to get to $70.20

Hope this helps! :)

From 1960 to 2010, a certain money stock measure was growing at the rate of approximately 43e(1/2)x billion dollars per decade,

natulia [17]

Answer:

1222 billion dollars.

Step-by-step explanation:

To find the total increase from 1960 to 2010, we need to find the growth of each decade and sum them all:

In the period 1960-1970, we have x = 1, and the growth is:

$y(1) = 43e(1/2) = 70.895$

In the period 1970-1980, we have x = 2, and the growth is:

$y(2) = 43e(2/2) = 116.8861$

The growth in the following 3 periods are:

$y(3) = 43e(3/2) =192.7126$

$y(4) = 43e(4/2) = 317.7294$

$y(5) = 43e(5/2) =523.8472$

So the total growth in the period 1960 - 2010 is:

$Total = y(1) + y(2) + y(3) + y(4) + y(5)$

$Total = 70.895 + 116.8861+192.726+317.7294+523.8472$

$Total = 1222.08\ billion\ dollars$

Rounding to the nearest billion dollars, we have a total of 1222 billion dollars.

Answer:

C

Step-by-step explanation:

There is a common ratio between consecutive terms

r = 24 ÷ 16 = 36 ÷ 24 = 54 ÷ 36 = 1.5 = $\frac{3}{2}$

This indicates the sequence is geometric with nth term ( explicit formula )

f(n) = a₁ $(r)^{n-1}$

where a₁ is the first term and r the common ratio

Here a₁ = 16 and r = $\frac{3}{2}$ , then

f(n) = 16 $(\frac{3}{2}) ^{n-1}$ → C
