mberisso

Answer:

Solving for m gives:

[tex]m=\frac{P-50}{5}[/tex]

which is option C in the list of possible answers

Step-by-step explanation:

Starting with the given equation, we work on using distributive property, and then on isolating the term with the variable to express:

[tex]P=5\,(m+10)\\P=5m+50\\P-50=5m\\\frac{P-50}{5} = m\\m=\frac{P-50}{5}[/tex]
