Question

Sal’s boss will contribute twice the amount of money Sal contributes to a relief fund, provided Sal contributes no more than $100. The function b(s) = 2s models the amount of money Sal’s boss will contribute, where s is the amount Sal contributes.

What is the practical range of the function?

all integers from 0 to 100, inclusive
all real numbers from 0 to 100, inclusive
all real numbers from 0 to 200, inclusive
all multiples of 2 between 0 and 200, inclusive

Answer 1

Which option do you think?

Answer 2

I'm not quite sure, I do not know how to solve it.

Answer 3

whatever amount sal will give, boss will give 2 times more
so whatever x will be b(x) will always be a multiple of 2

as range is from 0 - 100 (inclusive) then practical range will be 0 - 200 (inclusive )
now what will be your ans?

Answer 4

C?

Answer 5

correct. :)
