Question

Jenny invited Gianna to go watch a movie with her family. The movie was being shown in both 3D and on a regular screen. The cost of the 3D ticket was double the cost of the regular admission ticket. If r is the price of a regular ticket and d is the price of a 3D ticket, write an equation to represent the relationship between the two types of tickets.

Answer 1

d = 2r

Explanation:

r = price of a regular ticket

d = price of a 3D ticket

The cost of the 3D ticket was double the cost of the regular admission ticket

d = 2r

The equation that represent the relationship between the two types of tickets is d = 2r
