Answer: Multiplying the number by 2.5

Step-by-step explanation:

Jay took a number, n, and increased it by 25%. The value gotten will be:

= n + (25% × n)

= n + (0.25 × n)

= n + 0.25n

= 1.25n

After that, Then, he doubled the resulting product. The value now gotten will be:

= 2 × 1.25n

= 2.50n

Therefore, the equivalent will be multiplying the number by 2.5. This will be:

= n × 2.5

= 2.5n

Therefore, it's thesame with the value gotten.

The correct option is D.
