SOLUTION
For this problem, we need to use ratio and proportion.
We have: \frac{{weight\:on\:earth}_{1}}{{weight\:on\:moon}_{1}}=\frac{{weight\:on\:earth}_{2}}{{weight\:on\:moon}_{2}}
Let x be the weight of a person on earth who weighs 15 pounds on the moon.
Substituting the values, we have: \frac{200}{32}=\frac{x}{15}
Solving for x, we will get: \frac{200}{32}=\frac{x}{15} x=\frac{200\left(15\right)}{32} x=93.75
ANSWER: 93.75 pounds
