Step-by-step solution

To solve this problem, we will follow these steps:

  • Step 1: Write the equation based on the problem statement.

  • Step 2: Simplify and solve the inequality.

  • Step 3: Identify the range for Simon's age.

Now, let's work through each step:
Step 1: The problem states that Gabriel is 14 years older than Simon, so if Simon's age is S S , Gabriel's age is S+14 S + 14 . Given that the sum of their ages does not exceed 35, we can write: (S)+(S+14)35(S) + (S + 14) \leq 35

Step 2: Simplify the inequality:
2S+14352S35142S21 \begin{aligned} 2S + 14 &\leq 35 \\ 2S &\leq 35 - 14 \\ 2S &\leq 21 \end{aligned} Divide both sides by 2:
S10.5S \leq 10.5

Step 3: Given the inequality, Simon’s age is any number greater than or equal to 0 but less than or equal to 10.5. Since Simon must be a whole number, Simon's possible ages range from 0 to 10.

After reviewing the given choices, the correct answer falls within the range:
Between 0 and 10.5
