Question 150148: This problem is from a test. I have the solution, but I am unsure of where one of the numbers came from, so I would not be able to do a similiar problem on the final.
The class average on a math test was 82 out 100. The girls in the class scored 966 points. How many total points did the 8 boys score?
The solution I have looks like this:
966 + b/19 = 82
966 + b = 1558 (where does the 1558 come from?)
b = 592

Question 152106This question is from textbook
: I'm not sure if this is where I need to ask for help with this problem but I would really be thankful for anyone's assistance.
A book is opened. The product of the two facing page numbers is 9506. What are the numbers of the pages? Explain.
I set it up like this:
9506/2 = 4753 since on page is even and the other odd numbered I then continued 4753-1 = 4752. The pages are numbered 4752 and 4753 but this equals 9505 so it is incorrect.
What do you think? ThanksThis question is from textbook
