To solve this problem, we can set up an equation to represent the given information.
Let's represent the unknown number as "x". The quotient of a number and three can be written as "x/3".
According to the given information, four more than the quotient of a number and three is at least nine. Mathematically, this can be expressed as:
(x/3) + 4 ≥ 9
To find the solution, we can isolate the variable "x" by subtracting 4 from both sides of the inequality:
(x/3) ≥ 9 - 4
Simplifying, we have:
(x/3) ≥ 5
Now, we can multiply both sides of the inequality by 3 to get rid of the fraction:
(3 * (x/3)) ≥ 5 * 3
x ≥ 15
Therefore, the unknown number "x" must be greater than or equal to 15 for the given conditions to be satisfied.
