What is the value of the expression “eight more than three times the difference of four and a number” when n = 3?

 11

Step-by-step explanation:

Let the number is n

Then as per statement of the question

"Eight more than three times the difference of four and a number"

Expression will be [3(4-n)+8]

Now for n = 3

Value of the expression will be [3(4 - 3 ) +8]

                    = [ 3 × 1 + 8 ]

                   = 11
