The question says that someone on Mars weighs 38% more than what someone weighs on Earth. In order to answer the question, you need to know what 38% of 150 is. In other words, some number is 38% of 150. So you use this general formula: 

is/of = %/100

Substituting the values, we get: 

x/150 = 38/100

So now, you cross multiply and solve for x as I've done above. 

x = 57

So if 57 is 38% of 150, we have to add that to 150 because we know that the person on Mars weighs 38% MORE. So 150 + 57 = 207. 

Therefore, the person on Mars weighs 207 lbs.
