Final answer:
The expression is 24/x + 15. To find the quotient, divide 24 by x, then add 15 to the quotient.
Step-by-step explanation:
The expression you are looking for is 24/x + 15.
To find fifteen more than the quotient of 24 and a number x, we first divide 24 by x, giving us the quotient. Then we add 15 to the quotient.
For example, if x is 4, the quotient would be 24/4 = 6. Adding 15 to 6 gives us 21.
