At a graduation dinner, an equal number of guests were seated at each of 12 large tables, and 8 late-arriving guests were seated at a smaller table. There were 128 guests in all. If n represents the
number of people seated at each of the large tables, what equation could you use to find the value
of n?

A. 12n - 8 = 128
B. 12n +8 = 128
C. 8n + 12 = 128
D. 8n - 12 = 128

If n stands for number sold and c stands for cost per item, in which column would you use the formula: ? a. column d c. column f b. column e d. column g

You drop a rubber ball off the roof of a 50 meter high building onto a paved parking lot. it bounces back up with every bounce, but not quite all the way back up to you. after the first bounce it bounces back only 80 percent of the distance it was dropped from. the pattern continues, meaning after every bounce it comes up to just 80 percent of the previous maximum height. so if before the first bounce the height is 50 meters, what height does the ball reach after the fifth bounce? round your answer to one decimal place and chose the correct response from the choices below:
