I gave an exam to both of my sections of Math 110 semester. The first section earned an average of an 82 while the

second section earned an average of 74.

If there were 30 students in my first section and 40 student

s in my second

section, what would the average be if I combined the two sections? (HINT: You cannot just average the averages.)
