Question

help me

Answer 1

Well first we can cancel out D.
You see how it says 5 flights of stairs burns 1 calorie?
It should instead say you burn 5 calories every flight of stairs.

Answer 2

k

Answer 3

We can cancel C. because the graph would eventually show you burning more then 90 calories after 18 flights of stairs.

Answer 4

it actually tries to tell you that you burn 90 calories for only 5 flights of stairs which is wrong.

Answer 5

You understand?

Answer 6

yea

Answer 7

ok cool so now we can move onto and look at b

Answer 8

so the equation tries to say that c (calories) would equal f (flight of stairs ) + 5.

Answer 9

that would mean f equals 18 since it says flights of stairs.

so 18 + 5 = 23

Answer 10

that's not 90 so we can cross that out.

you get why ?

Answer 11

yes

Answer 12

ok cool,

so this leaves you with the final answer choice A.

Answer 13

although it doesn't exactly show 18 flights of stairs being = 90 calories burned.

continuing that answer choice all that way until the column on the left is at 18

it would say that you've burnt 90 calories in 18 flights of stairs.
