Blockbuster movie charges ten dollars for membership fee, and an additional three dollars and fifty cents for each movie rental. Write an equation to describe the cost, c , of renting x movies including the membership fee.
10 + 3.5x = c
c = 3.5 x + 10
To write an equation that describes the cost, c, of renting x movies including the membership fee, we can follow these steps:
1. Start with the membership fee: Blockbuster charges ten dollars for the membership fee. So, the initial cost would be 10 dollars.
2. Add the cost of renting movies: For each movie rental, Blockbuster charges an additional three dollars and fifty cents. Since we're considering x movies, we need to multiply the rental cost (3.50) by the number of movies rented (x).
3. Combine the membership fee and the cost of renting: The total cost, c, is the sum of the membership fee and the cost of renting x movies.
Putting all this information together, the equation to describe the cost (c) of renting x movies including the membership fee would be:
c = 10 + (3.50 * x)
