Answer:

D. 15 yrs old

Step-by-step explanation:

n×3+6=50 this is the number sentence so, to find what's the meaning of n we have to solve that number sentence the opposite way

50-6÷3=n this is the opposite way now it is time to solve

____

44

44÷3=14.6

then round the decimal to simplest form

and it is 15
