Answer:
The required expression is .
The value of the expression when y=20 is 2.
Step-by-step explanation:
Consider the provided phase.
3 less than the quotient of a number y and 4
The quotient of a number y and 4 can be written as:
Now 3 less than the quotient of a number y and 4 can be written as:
Hence, the required expression is .
Now evaluate when y=20.
Substitute y=20 in above expression.
Hence, the value of the expression when y=20 is 2.
