Answer:
Number is greater than or equal to 15.
Step-by-step explanation:
Let number be x
Quotient of number and 3 = [tex]\frac{x}{3}[/tex]
4 more than [tex]\frac{x}{3}[/tex]= 4+[tex]\frac{x}{3}[/tex]
4+[tex]\frac{x}{3}[/tex] is at least 9
4+[tex]\frac{x}{3}[/tex]≥9
Simplifying it ,we get
[tex]\frac{x}{3}[/tex]≥9-4
[tex]\frac{x}{3}[/tex]≥5
x ≥ 5(3)
x≥15
Number needs to be greater than or equal to 15
