20 out of 100 read 5 or more.

20/100 = 0.2

Now multiply the total students by 0..2:

275 x 0.2 = 55

55 people read 5 or more books.

Find two consecutive even integers such that the lesser added to three times the greater gives a sum of 46.
kvv77 [185]
N; n + 2 - the two consecutive even integers

n + 3(n + 2) = 46
n + 3n + 6 = 46   <em> |subtract 6 from both sides</em>
4n = 40      <em>  |divide both sides by 4</em>
n = 10

n + 2 = 10 + 2 = 12

<u>Answer: 10 and 12.</u>

1. Over the six months what was the average market price per share?
lozanna [386]
A) The average market price is (12 + 8 + 10 + 13 + 14 + 8) / 6 = $10.83

b) The total amount spent was: 12*8 + 8*12 + 10*10 + 13*7 + 14*7 + 8*12 = $577. The total number of shares was: 8 + 12 + 10 + 7 + 7 + 12 = 56. Therefore the average price per share was $577 / 56 shares = $10.30/share.
c) Since the cost per share in June was $12, and her average cost was $10.30, dollar-cost averaging worked in her favor since her average cost was lower.
