Answer from: gmaj

Number of computers Bytes sold in 2003 = 620
Number of computers Bytes sold in 2004 = 708
Then
Number of computers more sold by Bytes in 2004 compared to 2003 = (708 - 620)
      = 88
Percentage increase in the number of computers sold = (88/620) * 100 percent
      = 8800/620 percent
   = 880/62 percent
   = 14.19 percent
So the percentage increase in sales of Bytes from 2003 to 2004 is 14.19%. I hope this is the answer you were looking for.

Answer from: lb4628830

If you would like to know what is the percentage increase in the number of computers sold, you can calculate this using the following steps:

x% of 620 computers (in 2003) is 708 computers (in 2004)
x% * 620 = 708
x/100 * 620 = 708 /*100/620
x = 708 * 100 / 620
x = 114.19%

114.19% - 100% = 14.19%

The correct result would be 14.19%.

Answer from: Quest

geometric series converge the common ratio r has magnitude less than one.

$|r| < 1$

which is equivalent to

$-1 < r < 1$

for the example we need

|2-x| < 1

-1 < 2-x and 2-x < 1

x < 3 and x > 1

we can write that

answer: 1 < x < 3

1a. common ratio r=250/25=10 > 1 diverges

1b. r=50/100=1/2 converges

when these converge they converge to

$s = \dfrac{a}{1 -r}$

where a is the first term.

$s = \dfrac{100}{1 - 1/2} = 200$

answer: 200

1c. r=-1 so it's not the case that |r| < 1. diverges

2a. x is the common ratio so we converge when |x|< 1

2b. r=-10x / -2 = 5x.

we converge when

|5x| < 1

|x| < 1/5

2c. r=3-2x

-1 < 3-2x and 3-2x < 1

-4 < -2x and 2 < 2x

x < 2 and 1 < x

1 < x < 2

2d. [/tex] r=-48x^3/12 = 4x^3[/tex]

|4x^3| < 1

|x^3| < \frac 1 4

|x| < 4^{-1/3}

$|x| < \frac 1 2 \sqrt[3]{2}$
