Answer 3

To find the number that Ali is thinking of, we can follow the given steps:

1. Ali divided the number by 2.5. 2. He then subtracted 18.25 from the result. 3. The final result is 13.95.

Let's solve this step by step:

Let's assume the number Ali is thinking of is 'x'.

1. Ali divided the number by 2.5: - The result of dividing 'x' by 2.5 is (x/2.5).

2. He then subtracted 18.25 from the result: - The equation becomes: (x/2.5) - 18.25 = 13.95.

To find the value of 'x', we need to isolate it on one side of the equation. Let's solve the equation:

(x/2.5) - 18.25 = 13.95

To isolate 'x', we can start by adding 18.25 to both sides of the equation:

(x/2.5) - 18.25 + 18.25 = 13.95 + 18.25

Simplifying the equation:

(x/2.5) = 32.2

To get rid of the division by 2.5, we can multiply both sides of the equation by 2.5:

(x/2.5) * 2.5 = 32.2 * 2.5

Simplifying further:

x = 80.5

Therefore, the number Ali is thinking of is 80.5 (C).

Please note that this answer is based on the given information and the calculations performed.
