Three tickets to attend an off-broadway show cost $81 , 4 tickets cost $108, and 5 ticckets cost $135. a. show that the relationship between number an the cost is a peoportioalrelationship by making a table of tickets for 1 to 5 tickets.

Given,

The cost of 3 tickets = $ 81,

So, the cost of each ticket = = $ 27,

Let the price of each ticket is same,

So, the cost of x tickets ( say y ) = 27x

⇒ y = 27x

∵ For x = 1, 2, 3, 4 and 5 by making the table,

x          1              2               3             4               5

y         27           54             81           108            135

Thus, the price of 3 tickets is $ 81, price of 4 tickets is $ 108 and price of 5 ticket is $ 135

That is,

The equation that shows the given situation is,

y = 27x,

⇒ y ∝ x

Hence, there is a proportional relation between number of ticket and cost of the ticket.

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.
