I am thinking B, because if you think about it you would write it as x+ 8 because he first got x and then he added 8 more to that x and then they tell you how much they recived in those days if you multiply the like in answer D you will get to much and their askign for the total of teh 2 days so you would add them,... Hope this helped

Answer:
t=18 years
Step-by-step explanation:
A year has two semesters, then
n = 2v(t)=p(1+r/2)2t
3875.79 = 1900∗(1+(0.04/2))^2t
2.0398895 = (1+0.042)^2t
Apply natural logarithm on both sides
ln(2.0398895) = ln[(1+0.042)^2t]
Then simplify,
0.712896 = 2t∗ln(1.02)
t = 0.712896 / (2∗ln(1.02))
t=18 years
