<u>Step-by-step explanation:</u>
Quantity X Cost = Money Received
Adult: x 3 3x
Children: 500-x 2 2(500 - x) = 1000 - 2x
Adult = Children + 400
3x = 1000 - 2x + 400
3x = 1400 - 2x
5x = 1400
x = 280

B
Step-by-step explanation:
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.
