Answer 1

12 friends would pay $4 each

It would take 3.3 days to do the same amount

30 assistants would take 8 minutes to prepare the same amount

Explanation:

Answer 2

inversely proportional
4 ---------- 12
12 -------- x


`(4)/(12) = (x)/(12)`

`\boxed{x = 4}`

---------------------------------------------------------------

inversely proportional
6 -------------- 10
18 ------------ x


`(6)/(18) = (x)/(10)`

`18*x = 6*10`

`18x = 60`

`x = (60)/(18)`

`\boxed{x \approx 3,3}`

----------------------------------------------------------------

inversely proportional
4 ---------- 10 ----------- 60
30 -------- 10 ----------- x


`(4)/(30) * (10)/(10) = (x)/(60)`

`(40)/(300) = (x)/(60)`

`300*x = 40*60`

`300x = 2400`

`x = (2400)/(300)`

`\boxed{x = 8}`
