Answer:
b. [tex]\frac{p-1700}{10}[/tex]
Step-by-step explanation:
We have that the server's salary can be expressed as
[tex]p = $1700+$10t[/tex]
Counting the $ 1700 dollars as the fixed amount of your salary and contemplating the variable salary that would be $ 10 * t being t the number of overtime worked
from this expression we can clear the number of overtime worked by clearing t, so I finally have
[tex]p=$1700+$10t\\ $10t = p - $1700 \\ t= \frac{p-1700}{10}[/tex]
Done
