In a theater, there are 4 long rows of chairs, each with an equal number of chairs there are 5 ahort rows of chairs, each with an equal number of chairs on a crowded day, the ushers added 2 chairs to each long row and 3 chairs to each short row if x represents the number of chairs in each long row and y represents the number of chairs in each short row, the total number of chairs in the theater is given by the expression 2)sly 3) an equivalent expression is

An equivalent expression is 4x + 5y + 23

Step-by-step explanation:

There are 4 long rows of chairs and 3 short rows of chairs.

Let x be the number of chairs in long rows and y in short rows.

So total number of chairs in theater

C = 4x + 5y

Now on a crowded day 2 chairs were added in long rows so number of chairs in long rows becomes

= 4 (x + 2)

Similarly ushers add 3 chairs add in short rows so total number of chairs in short row = 5 ( y + 3 )

Now total chairs in theater

C' = 4 ( x + 2 ) + 5 ( y + 3 )

= 4x + 8 + 5y + 15

= 4x + 5y + 23

C' = C + 23   [Since C = ( 4x + 5y ) ]

Number of chairs added were 23 as compared to normal days.
