Math help

Answer 1

@ospreytriple A right?

Answer 2

I don't understand the funky square brackets. What do they mean?

Answer 3

I think they're just like parentheses...

Answer 4

Don;t think so. I'll see if I can find out what it means.

Answer 5

@satellite73

Answer 6

Sorry. Can't find it. So I don't know the answer to the question. But I'm certain it isn't A. Good luck.

Answer 7

I think it's D...

Answer 8

the reason i think its last option
let d=3 days
then 125*3=375 so in 3 days the cost for renting a car would be 375..., where d=d

125(3-1) if d<d
we get 125(2) where d<d
so 250 where d <d
and since in 3 days d=375 ...we see that using this ... 250 is less than 375

Answer 9

Ok thanks so much!

Answer 10

if you use the 3rd option we get
let d=3 days then
125(3+1) which =500 is not less than 375

Answer 11

The double use of brackets indicates integer to "d"
for instance,
[[1]] = 1
[2.7]] = 3
etc.,
