Atheater has 25 rows of chairs. the first row has 18 chairs, the second has 22, and the third has 26, and so on. in total, the theater seats people.

In total, the theater seats 1650 people.

Step-by-step explanation:

Given : The number of rows in the theater = 25

The number of chairs in first row = 18

The number of rows in the second row = 22

The number of rows in the third row = 26

The common difference in the number of chairs for the consecutive rows =

Thus its a Arithmetic progression.

Let n be the number of rows and d be the common difference , then the total number of chairs in n rows is given by :-

, where a is the umber of chairs in first row .

Put a = 18, d=4 and n = 25, we get

Hence, In total, the theater seats 1650 people.

answer: 40392

step-by-step explanation:

10098 x 4 = 40392

step-by-step explanation:

well if you round, things become much more simple. round 5.95 to 6, 4.25 to 4, and 1.05 to 1. now, add 6+4+1 and that would equal 11. so the items together would equal to about $11.
