Homework Help: math,help, algebra

Posted by Jasmine20 on Saturday, January 27, 2007 at 8:31am.

okay i have a table it reads.
It has 4 colums

Title population of Europe by age groups (population is in thousands)

First colum it reads down like this
age 0-14
age 15-64
age 65+
age 75+
total

second colum it reads
(In 1950)
143,175
359,162
44,981
14,553
547,318

third colum it reads
(In 1970)
166,367
421,432
68,642
22,762
656,441

Four colum reads
(In 1995)
139,464
487,110
101,338
38,139
727,912


the question asks between 1950 and 1995 , did the european population for age 15-64 or for age 75+ in crease by a greater percentage?


Now how do i figure this out can someone set up as an equation for me.Please

You have to calculate the population increase for each age group and compare.


percentincrease=(newpop-oldpop)/oldpop * 100

I don't know if i am doing this right. but this is what i did and what i got.

for the ages: 15-64

In 1995/In 1950 (100)=%

(487,110)/(359,162)*100=135.62 so i rounded and it would be 136.00 so if i move two decimal places over to the left the answer would be: 1.36%

For ages 75+
THen (in 1995)/(in 1950) (100)=%

(38139)/(14553)*100=262.06 so if i round the answer it would just be 262.00 which if i move two places to the left i get: 2.62%

so the the one that got the greater percentage was ages 75+

Why did you move the decimal place to the left? That makes no sense to me. Did I put that in the formula?
