Answer:

When
, the value of the expression is 
Step-by-step explanation:
By definition, when you divide two numbers, the result is known as the "Quotient":
Notice that "c" is the quotient of "a" and "b".
Therefore, the expression for "the quotient of a number
and 4" is:

Now, "3 less than the quotient of a number
and 4" indicates that you must subtract 3 from
; so you can conclude that the expression is:

Substitute
into the expresion:

Evaluating, you get that the value of the expression when
is:
