Question

the national debt of a small country is $6,330,000,000 and the population is 2,964,000. What is the amount of debt per person?
** im putting the exponents in parenthesis**
A. $2.14 x10(6)
B. $21.36 x 10(2)
C.$2.14 x 10(3)
D. $2.14

Answer 1

The easiest way to compute this is to drop the thousands hundreds and one on both numbers. So 6,330,000,000 becomes 6,330,000 and 2,964,000 becomes 2,964. Then divide 6,330,000 by 2,964 and you get $2,134.63 per person. Which is just about answer B. 21.36 x10(2).

Answer 2

C 2.14*10^3

Answer 3

You have the dollars ($) and you have the # of people, so you divide the two.

In the end your are looking for the number of dollars per person, or $/person. You have the $'s ($6,330,000,000) and you have the # of people (2,964,000)...

So it would then be $6,330,000,000 / 2,964,000.

As far as the answers go look at the 'x10 (#)' as decimal points. All that stuff at the end does is move the decimal point in a direction. Since the #'s are positive, if you want to take that end stuff out and just see the actual number, you move the decimal point to the left.

So then
(A) would become 2,140,000.00
-I moved the decimal point 6 places to the right (and so on)

I'll leave you to use a calculator and figure out the rest

Answer 4

B and C would both work, B is more correct however.
6,330,000,000 divided by 2,964,000 is 2135.627 . . . .

B. 21.36 x 10(2) = 2136 or
C. 2.14 x 10(3) = 2140

Answer 5

B. - The answer is 2,136 which is also 21.36*10squared

Answer 6

you just divide the debt by the population. answer is letter b.

Answer 7

B. debt/#people.

Answer 8

well..im guessing this one is the simple maths..just divide them..the answer is C

Answer 9

c

Answer 10

b 21.36
