Answer:
B
Step-by-step explanation: By breaking down the question, you can see that Jasper (j) is 3 times as old as Kevin, which means you need to multiply jasper's age by 3. The question also says that Kevin is 4 years older than whatever 3 times Jasper's age is, meaning you need to add 4 years into the question. The only answer that involves multiplying by 3 and adding by 4 is B.
