Question 976429
<font face="Times New Roman" size="+2">


There were 10 questions in the first part of the test and *[tex \Large x] questions in the second part of the test, so the total number of questions was  *[tex \Large x\ +\ 10].  The person taking the test scored 9 points on the first part and *[tex \Large 0.3x] points on the second part which is half of the total questions, so:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 9\ +\ 0.3x\ =\ \frac{x\ +\ 10}{2}]


Solve for *[tex \Large x] and then calculate *[tex \Large x\ +\ 10].

My calculator said it, I believe it, that settles it
