The table shows the cost of movie tickets based on the number of tickets purchased. PLEASE HELP ME

Number of Tickets Cost

2 $17.00

3 $25.50

4 $34.00

5 $42.50

Based on this proportional relationship, find the constant of proportionality (r). Using the value for r, enter an equation that will calculate the cost (y) of x movie tickets in the form of y=rx. The answer is not y=8.5 Please help the one who gives me the correct answer will get brainliest

Respuesta :

The proportional relationship is given by y = 8.5x

Two variables are said to be proportion if an increase/decrease in one variable causes an increase/decrease in the other variable.

Let x represent the movie tickets and y represent the cost.

Since x and y are proportional, hence:

y ∝ x

y = rx

Where r is the constant of proportionality.

From the table to find x, when y = 17, x = 2, hence:

17 = 2r

r = 8,5

y = 8.5x

The proportional relationship is given by y = 8.5x
