Answer :
Given the ratio of an object's weight on Earth to its weight on Neptune is
[tex]$$5:7,$$[/tex]
we know that for every 5 units of weight on Earth, the weight on Neptune is 7 units. This can be interpreted as finding the weight on Neptune by multiplying the Earth weight by the conversion factor [tex]$\frac{7}{5}$[/tex].
For a person who weighs 150 pounds on Earth, the weight on Neptune, denoted as [tex]$W_N$[/tex], is calculated as follows:
[tex]$$
W_N = 150 \times \frac{7}{5}.
$$[/tex]
First, compute the conversion factor:
[tex]$$
\frac{7}{5} = 1.4.
$$[/tex]
Now multiply the Earth weight by this factor:
[tex]$$
W_N = 150 \times 1.4 = 210.
$$[/tex]
Thus, a person who weighs 150 pounds on Earth would weigh 210 pounds on Neptune.
The correct answer is [tex]$\boxed{210}$[/tex] pounds.
