Question

Someone Please Help!!!!

Researchers count 30 tagged zebras and 150 total zebras in an area of a game reserve. If researchers had previously tagged 80 total zebras at the game reserve, about how many total zebras live at the game reserve? Write a proportion to estimate the total population.

Answer 1

@campbell_st @thomaster Please help me with this......

Answer 2

Try setting up your proportions as 30 over 150 equals 80 over x. Then, solve for x.

Answer 3

Can you help me as in "What would x be?"

Answer 4

To solve for x, you will need to cross-multiply. Are you familiar with that?

Answer 5

no......Sorry im kinda new to this........

Answer 6

ok, your equation when set up will look like this:

\[\frac{ 30 }{ 150 }=\frac{ 80 }{ x }\]

Answer 7

You will cross multiply to get: \[30x = 80*150\]

Answer 8

do you know how to solve for x from there?

Answer 9

Not really..... Can you help me a little bit more?

Answer 10

Alright, multiply 80 and 150 together and tell me what you get.

Answer 11

12000

Answer 12

Alright, now how would you get X by itself?

Answer 13

Do you divide12000 by 30?

Answer 14

You sure do.

Answer 15

And then the answer to that will be what x is?

Answer 16

And that will give you your approximate number of total zebras, yes.

Answer 17

Thank you so much!!!!

Answer 18

No prob, take it easy.

Answer 19

Ok, you 2
