Answer 1

2.75 cups were in the punch bowl before felicia refilled it .

Explanation:

Here we have , the punch bowl at felicia's party is getting low so she adds 12 cups of punch to the bowl two guests serve themselves 1.25 cups and 2 cups and 2 cups of punch the punch bowl now contains 11.5 cups of punch . We need to find how many cups were in the punch bowl before felicia refilled it let n=number of cups bowl before felicia refilled it. Let's find out:

Initially we have , n number of cups of punch ! Than 12 additional cups were added , given below is the equation framed for the number of cups present:

⇒
`n+12`

Now , After this 1.25 and 2 cups were served by guests themselves and remaining cups were 11.5 i.e.

⇒
`11.5+1.25+2`

⇒
`14.75`

Equating both we get :

⇒
`n+12=14.75`

⇒
`n=14.75-12`

⇒
`n=2.75`

Therefore , 2.75 cups were in the punch bowl before felicia refilled it .
