Answer:
![t=(p)/((s_1-s_2))](https://img.qammunity.org/2020/formulas/mathematics/middle-school/tum2aapv8dx193tf6supofqs8weort6qm8.png)
Therefore, C is the correct option.
Explanation:
We have been given the equation
![p=s_1t-s_2t](https://img.qammunity.org/2020/formulas/mathematics/middle-school/shau9kkak3t2qtk13lvsgermkflevmzd0q.png)
The GCF of the right hand side of the equation is t. Hence, factored out the GCF.
![p=(s_1-s_2)t](https://img.qammunity.org/2020/formulas/mathematics/high-school/gun4jmsvbyi81l7ltnuno1v2jzop84pdv7.png)
Now,
is in multiplication with 't'. So in order to isolate t, we can divide both sides by
![t=(p)/((s_1-s_2))](https://img.qammunity.org/2020/formulas/mathematics/middle-school/tum2aapv8dx193tf6supofqs8weort6qm8.png)
Therefore, C is the correct option.
