Step-by-step explanation:
We are given that
Number of markers in a box =15
Total number of friends=4
Number of markers are given to each friend=3
We have to find the expression that can show the number of markers Tim has left.
To find the number of markers Tim has left we will subtract the number of markers given to 4 friends from total number of markers in a box
Number of markers are given to 4 friend=
Number of markers Tim has left=
Hence, the expression which cans how the number of markers Tim has left
