Answer:

x = 5

Step-by-step explanation:

These triangles are similar, so they are in proportion to each other. Because of this we can say $\frac{2.5}{3.5}$ (the lengths of the vertical sides) = $\frac{x}{7}$ (the lengths of the hypotenuses). If we solve by cross-multiplying the numbers and then dividing we get x = 5.

Sloan [31]

If two tickets cost $16.50 you have to find the cost of one ticket by dividing 16.50 to 2 which is 8.25 (this is the cost of one ticket) then to find the cost of five tickets you have to multiply 8.25 by 5 which is $41.25 is your answer
