Question

Denise is designing the seating arrangement for a concert at an outdoor theater. To give everyone a good view, each row must have 6 more seats than the row before it, and the 1st row can only have 11 seats. Explain to Denise how to create an equation to predict the number of seats in any row. Then, using your equation, show your work to determine the number of seats in row 18

Answer 1

Answer:

Explanation:

Work out the equation:

1st row is 11 seat and the seat after it will be 6 more and 6 more after the second row and so on. This can be written:

6(x - 1) + 11 =

Where x determine the number of row.

Ex: if x = 1 thus, 6(0) + 11 = 11 seat which is the first row.

Find the number of seats in row 18:

6(18 - 1) + 11
6(17) + 11
= 102 + 11
= 113 seats
