Question

HELP!! There are 78 students from a local high school attending a concert. The concert hall has 40 rows of seats. The first row has 50 seats, and each row after that has 4 more seats than the one before. If all 78 students sit in one row and are as close to the front row as possible, in which row did the students sit?

A) row 7
B) row 8
C) row 11
D) row 12

Answer 1

Row 8 

Here is a trick, add 4 to 50 until you get 78 or above.

50+4+4+4+4+4+4+4 = 78, and I added 4 seven times! This means that all students can sit in row 8

Answer 2

The row in which the 78 students who are attending the concert would sit is row 7.

What row do the students sit?

The equation that can be used to determine the row in which the 78 students sit is:

Row the students would seat = (number of students - number of seats in the front row) / rate of increase in seats

(78 - 50) / 4

28 / 4 = row 7
