For the first question the correct form would be B. It would be 6(p-3)=42. For the second question the answer would be 10.

Step-by-step explanation:

For the first question B is correct because it's 3 dollars off which would be -3.

For the second question you would multiply 6 with p and 6 with -3. This would equal to 6p-18. This would make the equation 6p-18=42. You would then add 18 to 42, which equals 60. Finally you would divide 60 by 6, which equals 10, which is your answer.
