You are correct. The answer would be B. When you look at this equation, look to see where the parenthesis are located. Parenthesis mean multiply. So if we took them out, the problem would look like this:
4 × 1 × c + 1 × 7
Because the multiplication sign comes after the 4, you are multiplying the (4 + 7) by 1, not 4.
I hope this makes sense. Please let me know if you need any more help or clarification. Good luck!
