Asap ill do anything

if you traveled through space and landed on an unknown planet where gravity is 15 times as strong as the gravity on earth, how much would you weigh on this new planet if you weighed 100 pounds on earth?

Use the equation 
W=mg 
where w= weight 
m= mass
g= gravity 

First, convert 100 pounds to kg (use the online conversion) which should be 45.3592 kg afterwards. Then, convert kg to mass by dividing the constant of gravity on earth, 9.8N (I believe). Then, use the equation and you should be good to go. 

Hey i m confused bw c and d. but i think u can go for c
